Pandaria Unholy Death Knight

[Gingerkids]

recently i started playnig death knight here, and people told me unholy is bugged and that I should go frost. But there are people telling me its not THAT bugged and that is viable to play. So my question is what exactly is bugged here? Is is really viable to play in arenas/bgs? Are bugs really gamebreaking as they say?

thanks

Unholy good now , looks like frost dying , dw bugged to death , 2h paper vs other classes who crits u 160k each spell , so unholy will be good .
found funny thing on unholy , Shadow Infusion make dk 50% more dmg , but i think must be only ghoul , not dk

Unholy was good even with the bugs you could dish out same damage in bgs as frost if you know what you are doing. 2h>dw anyways, my frost seems pretty good, ony locks hit me for that kind amount of dmg but i hit them back harder, them and their friends.... shadow infusion is 5 stacks max, 10% extra damage for the pet per stack.. do you even know what you talking about?

OT: They are playabe-ish, you need to try extra hard to know to play UH, 1v1 they are too good... Fix reaping totally and it's pretty much good to go..

Shadow Infusion stacks visually on the DK's Buff bar, this was a simple UI Improvement released in a patch for DKs to give them a little more awareness of their pet. It has absolutely no influence on the DK itself, it is purely cosmetic.
