RE: Poll - None of the above.
If anything, remove heirlooms completely and bake the XP bonus in (toggle-able, obviously), whilst increasing it further for every char you already have maxed. Can keep them as a cosmetic set, or just a set that works as a basic levelling blue set with no real advantage other than the slot being filled constantly with something decent.
Other than that, leave them as they are. If I want to level fast I can - If I don't, then I won't use them.
Turn them into enchants you can put on your gear for the xp bonus.
- Add heirloom boots/belt/gloves (for transmog purposes)
- Reduce the bonus xp to 3-5% per visible item (weapons excluded)
- Remove the bonus xp from other items
Leave them as they are. Even without heirlooms, the leveling is ridiculously mediocre. There won't be a challenge nor would I be happy to put up with that aspect of the game even longer than I have to.
Leveling is suffering. I like it to be sped up as much as possible. If you don't want to level quickly, save your gold by not purchasing heirlooms.
That works fine until you get into a dungeon or PvP where virtually everybody else has heirlooms and either they act like asshats because they think they're awesome due to how overpowered heirlooms are, or you simply can't touch them in PvP because of how overpowered heirlooms are.
The problem with heirlooms isn't the XP bonus, it's how they outclass by a wide margin the gear of a non-heirloomed player.
Therefore, the problem with heirlooms goes far beyond "don't use them if you don't like them." They affect everybody who plays, even (and especially) if somebody chooses not to use them, or doesn't have them.
Heirlooms only scale to rare quality and i have never been in group where someone got chewed out for not having looms.
As for pvp well thats a different story but then if you want to level up doing pvp then you should know the risks and if you dont you sure as shit will learn the risks.
Remove them completely. They were a terrible idea to begin with (IMO). This coming from an altaholic BTW.
I come across a quiet river, that wonders through the trees.
I stare into its running waters and fall unto my knees.
In resignation to the forest, that's held me for so long.
I close my eyes and drift away into nature's evensong.
I'm guessing the answer might be, if you wouldn't\couldn't have leveled them without the heirlooms boost "you don't deserve to have them". I think gamers, or at least MMO players or maybe just WoW players are very strong into the Old man syndrome. "Back in my day we walked 10 miles, up hill, in the snow, both ways! and we were happy!" Now get off my lawn!
The thing is New players cant afford heirlooms and if blizz doesn't want new players buying heirlooms from gold token then they can stick restrictions on heirlooms like you need at least 1 non boosted level 100 to purchase them so they have to experience it the old skool way first time liek we all did.
But to purposely gimp yourself when all you want to do is level up your alt fast seems insane to me i honestly cant see why people want to get rid of looms especially in legion where blizz seems to want you to explore each class and artifact weapon.
I am sure from seeing this that you have Never seen a new player, or interacted with one. My gf's friend started up in MoP and it took her several months to hit max level. Why? Because she wasn't optimized for stats, rotation, or even questing areas.
Its not "mythical new players", its the truth. New players Will have it harder while veteran players will, of course, find the leveling process crap when they are on their 3rd+ alt. That is how it works.
The system has problems, like being out leveled for a zone thanks to 1 dungeon, but not high enough to start the next. Or how you have to go from start to finish in a zone vs starting further in.
There are best quests and best zones. Have you never leveled outside of dungeons? You don't stay in silverpine as a level 20. You go to the next area. You don't stay in borean at level 75, you go to the next zone for Much better exp from quests. You don't skip a dungeon quest, which will generally give a ton more exp then a regular quest. There is a optimum way to level. Veteran players know them. New players don't. It wont even occur to a new player to move onto the next zone before the one they are on is finished. Heck, that is assuming they can find it.
There is also skill involved. A new player spamming frost bolt isn't going to be as skilled as a veteran using their fingers of frost procs. Or a new player who isn't using taunt on a pet. Can they two shot a mob? Sure. However, its less likely at higher levels and that is when the skill difference shows most between a new and a veteran player.
So, it has its problems, but like I said, being a veteran player only furthers those problems by a great amount. New players still take a long time and find it difficult. Personally, I don't see a need to change it. Everything is at max level. The tuning for the classes, the best content, PvP balance, everything is worked for max. Leveling can be fun, and should be, but you can't expect them to spend time on it when everything of importance is for max levels and there is no reason Not to be max level.
