My first impression as a healer - played the class since the very beginning - is that it got a lot weaker. Maybe it's my rotation, build and rubies but I noticed a serious drop in my dps... and frenzy is 90% useless... And I have 8 talent points without any clue where to use them since I ran out of useful skills in PvE unless I take heals which are mostly useless in DPS speck. Also I'm not sure are the 3 stamina rubies working at all.. it's supposed to buff 60% more stamina but I didn't notice anything.
By far, I don't like the class changes
Edit: The effect of the stamina rubies has been applied now... without them I had circa 730k stamina, now I have over 1 million... Dps however remains much poorer. Probably gonna revamp the build and drop out frenzy completely. Also what Aionwen said about the old Cleansing Flame - it's so useless even if it's supposed to be one of your main skills now!!!!! Even with proper rubies, the cd is way longer than the ticks last and the damage the ticks do is poor. Also, the 55 yards ruby buffed skill range is back on being the lousy 40 yards >.>
Also I dislike the new way of party buffs and the limitation the specific aspects brings to all classes now just kills the variety.
