I honestly don't understand the argument that PoE can be played forever but D3 gets boring. They have literally the same end game - endlessly grinding randomly generated dungeons. D3 at least has the luxury of Paragon levels. What does PoE do? Lets you get to about about mid 80s before ramping up the obscene amount of experience required to get higher. It is quite a feat to hit 100 in PoE. I'd say probably the same amount of grind as hitting Paragon 2000 in Diablo 3. Maybe even more if you're efficient at it. What PoE does is make min-maxing almost impossible, whereas with enough time and luck in D3 you can manage to get BiS gear with perfect rolls fairly easily.
The entire point of PoE is to endlessly grind currency so you can either create your own gear, and all the endless frustration that brings, or use it to buy the things you need from other players. Which just encourages buying currency from third-party sites (there are even sites where legit players can sell their currency, so you can stay away from shady Chinese farmers) in order to get the gear they need. If anything, the only thing PoE has that D3 doesn't is forced multiplayer interaction, unless you play SSF, which to me is stupid because the entire system on which PoE is built is counter intuitive to playing solo.
Don't get me wrong - I've been playing PoE since launch, I still have all of my Silver supporter stuff, and I will continue to play it. But the way people bash on D3 in support of PoE is just silly, considering how so much of both games are similar.
Actually they cannot be as far apart as they are.
D3 has GRs.
PoE has Atlas, Delve, Temple Runs, Syndacate, Bestiary crafting, and add on top of it every single League mechanic that made its way into standard game.
It's not a problem of content type - in fact, so many people like GRs. The point is purpose and variety.
D3 GRs are randomized dungeons that exist for the sake of it and getting a +1 to a legendary gem.
In PoE, you have many different kind of progressions all aimed to hunt items or currency - which is what people like. It's not about zerging hordes, it's why and how you do it.
I see them as two completely different beasts and PoE is hands down superior to D3 in this aspect.
Non ti fidar di me se il cuor ti manca.
The push starts when you fail a GR, I am mister obvious here.When does "the push" generally start?
Personally I don't push, I stop my season when I hit guardian. Admittedly I wanted to push this season with my Crusader, but stopped mid way. I don't want to do 100 tries just so I could get the perfect rift (Also, my weapon and amulet needed more farm so I could change them.).
In the end, it's YOU who decide anyway.
As for the comparaison between your necro and your crusader, there is unbalance between the classes in Diablo, this is true. The best SOLO pushing class atm is the Wizard, by a really good margin. It's not the crusader though, the crusader can't GROUP well on top of that.
You need better gear/or a better set altogether for your necro, that's it. (Icy-veins . com is your friend, but you need to think about it yourself. I followed a blood spec necro guide from Icy-veins some season not that long before, and I only pushed GR75)
If I had to redesign paragon levels I would have them increase the effect of items by a percentage. Granted that won't affect procs, but DPS and stat bonuses, yes.
This way your items are still the most important. Sure a huge paragon level is better than a low one, but the goal of getting the best items would stay the same.
