Quoting Obelodalix from previous thread where I was told I was wrong or lying "Far as the 100% haste goes - that didn't happen either. 5 stacks from GoAK and DF amount to 70%, you can't really get 30% extra in PvP gear. You didn't see what you think you saw."
Didn't realise GoAK gave haste now, and as it gives 50% and different haste sources stack multiplicatively, 100% is indeed possible. With the 4.38% haste said Paladin had from gear it is:
1 * 1.0438 (gear) * 1.1 (Seal of Insight) * 1.2 (Divine Favor) * 1.5 (GoAK)
That's plenty over 100% haste, more like 107% - got my res cast down to 4.83seconds
Also, just tested in game on my own paladin, being hit while in bubble does NOT put you back in combat, I managed to get the res off, just liek I saw in arena earlier.
So yeah, I was right, go test it...
EDIT: just tested without ressing, if you are not in combat when you bubble, any actions taken by other players towards you will NOT put you back into combat. It's either a bug, or no-one has ever noticed it before.
EDIT2: tested again with other paladins, and other opponents, this seems every temperamental and likely dependant on something or a combination of somethings. No idea what though.
