"I don't always WOG, but when I do, I prefer Dos Equ...err...5-stacks" - Most Interesting Paladin in the World
I feel like the bonus will be basically a consolation prize (much like t15) for when we DO have to WOG while we are progressing, and will become a tool to game HoPo/ShotR uptime once we outgear everything. Is it so much to ask to have a bonus that's useful during progression again?
Look at the DK set bonii - The DRW changes and the set bonus give any half-decent tank a semi. No more RP cost on DRW, and when you pop it with 4pc, you get all FU runes back as D runes AND you get FOUR FREE DS'S! That is just insane! Hell, even the 2pc (every 4 BBs, HSs or RSs give you an extra bone shield charge) is head and shoulders above anything we get.
Instead, we get a mini-game that basically offers us the choice of gaming one of our "saves" for a moderate increase in HoPo when palyed properly, IF we choose what has almost unequivocally been subpar gear (vs haste off-pieces). Plus, as you surmised, if one was to go for the 2t15+2t16 combo, we'd likely see commensurate breaking of the bonus to prevent ridiculousness. Even though, as I posted earlier, the 2 set bonii work against each other already AND it would force us into very poorly itemized gear.

And no, I see no reason to ever use 2+2 as their mechanics are diametrically opposed on efficiency. You'd be shooting yourself in the foot unless it was some crazy amount of adds you were tanking.
Basically, my stance is this:
The 2pc is not BAD. I will likely get it and use it, but not before my 2 warlocks, our disc priest and our ret/holy pal get their tier. It provides an interesting playstlye change, but not one that is conducive to "average" players. I wish, instead, that we had gotten bonii more in line with the DK set (2pc passively increases a minor CD, 4pc greatly increases effectiveness of a larger CD). We got the same "formula" but not the same effect.
