Going over the newly-released tier 8 class set bonuses, it occurred to me: maybe these set bonuses a testing ground for new class mechanics?
A number of set bonuses cause certain dots to crit. They seem at first glance to be ludicrously overpowered. Are they simply using the bonus to test the effects without them going class-wide? This way fewer people will complain about nerfs if the changes have to be rolled back. Maybe in 3.2 the set bonuses will be changed and the critting ability rolled into the base abilities of the class, or talents.
Also, Protection warriors get a set bonus where Shield Block also grants you 20% reduction to magical damage taken.
Um...guys? It seems like that set bonus is going to be required for warriors for any fight like Sarth 3d that dishes out big bursts of nigh-untankable magic damage. I'm already hearing reports on the PTR of bosses that require a DK tank with clickable anti-magic cooldowns. Compared to DKs, warriors and paladins heavily lack on-demand defenses against magical damage. Hopefully this set bonus will be rolled into the base ability, and paladins will also be given some similar anti-magic clicky to make hard modes a bit more fair to small guilds like mine who don't happen to have a DK or Feral druid to tank those encounters.
Otherwise, you're going to see that same crappy phenomenon I was bemoaning in my last post: Warriors holding on to 4-piece tier 8 in their bags to allow them a fighting chance to tank a firebreathing boss in tier 10, since otherwise they'd just have to sit out for a DK.
And for the record, I think shield block should have also worked on magic damage from the moment Wrath was released. The fact that the devs haven't added it in yet is a travesty.
Seriously, get your act together, Blizz. It really shakes my faith when some guy who spends an hour a day reading about warcraft can see these things coming a mile away (as does the entire WoW community), and yet the people whose job it is to design the classes just don't seem aware of this stuff.
So I prefer to think it's an intentional testing ground, and many of these changes will be rolled into the classes themselves or talents once the devs see how they pan out in practice.
