1. Why would you want to rank it 2+ anyways? 61 is the only pvp level where this actually is a problem.
2. Lol why?
3. Yeah it should last longer, 10 seconds would be perfect IMO. What you mean with "it should be able to evade crit"?
4. Hit buff? You don't need to have that active 24/7.
5. Dodge debuff, h/s debuff, stun, super high damage when combined with rabid bite. Not enough for you?
6. Don't use if you don't like. Movement debuff and decent damage are actually pretty cool things.
7. Lol, do you mean that is should debuff like 200 armor?
8. It does damage too, so maybe not.
9. Not usable? Seriously? It boosts your damage by huge amount, and you think it's useless just because its active only 71.4% of the time?
