Is it possible it's broken? I know Gargolye is broken in beta and doesn't even do one deathcoil worth of damage the entire time he is out.
It is working as intended, it attacks and builds stacks and everything just fine. It is just extremely underwhelming, the burst explosion at the end is pathetic now, hits for about 4-5k in PvP :(.
The explosion really should do no less than 30k in PvP, and 50k or so in PvE. Otherwise any possibly damage from it is easily lost within a standard deviation by a few crits more or less.
I agree completely, except the devs seem to disagree. The original version that actually added a reasonable amount of damage was pretty much perfect for a 5 minute cooldown (it was about 500dps used on CD) but it was insane iWin button in PvP because the explosion was hitting for 100,000 on resil. The obvious fix was to reduce the damage and the cooldown, you can keep that 500dps used on cooldown without it being a massive burst cooldown, at two minutes it would only have to be 60k in PvE, which is 40k in PvP or about the same as a single crit lavaburst (LOL).
Instead they went with this extremely convoluted backwards fix of making the burst at the end useless and changing it officially to our third straight up "this button buffs your damage" cooldown by removing a bulk of the guardians damage while increasing the buff it gives you.
Now we have the exact some problem we had with the original 100k explosion version (I call this the original because it was the first version that was balanced in at least one aspect of the game, before this version it was awful for a long long time, then retarded OP with 380k explosions for a few days), when we are able to pop GoAK+ AW + Zealotry on a target we will be able to absolutely annihilate them inside a HoJ. For the benefit of the non-rets that don't know what all these cooldowns do, a 20 stack(it takes 10-15 seconds to build to 20 stacks) GoAK gives +20% strength, AW gives + 20% damage, and zealotry makes your CS give max combo pts. With all three up at full strength at once you can expect 50k TV crits every other GCD essentially, it gets very dirty very fast. Ret is the new three minute mage, run into us when we have everything off cooldown expect to die veyr very quickly, the rest of the time we are a free HK.
