Replacing JP/VP gear with bonus rolls is the most idiotic thing Blizzard can possibly do. Add that to the fact that reforging is gone only makes this expansion the most gear grindy yet.
With the pre 5.4 gear system - This 522 item cost 1250 valor, if I get terrible luck with loot drops this week there is a 100% guarantee that I will get an upgrade within 2 weeks.
Post 5.4 gear system - Even though they gave me an increased chance to get loot every time a bonus roll fails, there is no guarantee I will even get an upgrade this month. Hell I probably could go 2 months without getting a damn thing.
In WoD they say they'll put in a system that makes it so you are "less likely" to get the same item twice. I'll give you 3 reason why this is a terrible change.
1. In WoD raids, every piece of gear will have random secondary stats. So let's say Boss 1 drops cloth gloves and you get crit/haste gloves but you want mastery/haste gloves, will the bonus roll system give you a less likely chance to get those same gloves because you already got them before? Even if the randomized secondary stats you got on the first pair were shit for your spec? What if you don't want the same gloves? 2 sides of this system and only 1 of them will be put in.
2. Fixing RNG with more RNG is never a good solution.
3. We can still (and some people will) go weeks and possibly even months without a upgrade as with the VP gear system, we *knew* we were getting an upgrade within 2-3 weeks.
Only thing WoD is doing is making the gear grind more grindy.
