No idea if anybody has posted similar ideas but im going to post em anyway. Feel free to input feedback
1) Change to Improved Chain Heal:
Increases the amount healed by your Chain Heal by 10/20%, also, when 2 or more jumps of a Chain Heal crit, you have a 50/100% chance to consume a Water Shield charge.
This would allow our best heal to benefit from crit based mana regen, as i foresee the downrank nerf killing our mana with Chain Heal
2) Reverse Tidal Waves. After you cast a Healing Wave or a LHW you reduce the cast time of your next 2 Chain Heals by 30%. Maintain the extra bonus healing to HW and LHW.
3) Put back Spirit Link, an ability i was really looking forward to playing with, looked to be very original and unique to the shaman class that Blizz scrapped because they didnt feel like putting the time and effort into balancing and fixing the problems with it. Or, buff riptide hugely, as it stands its a terrible idea for a 51pt talent, and raising how much it heals doesnt change much. I heard an idea somewhere about chain heal spreading the riptide HoT effect (and possibly even the 25% boost to CH), which given proper balancing wouldn't be OP and would allow us too keep up with other healers.
As far as i see, our talents seem to make us lean towards the new tank healers, and if thats the case, im re-rolling or respeccing. Most likely respec because i love the shaman class more than any other despite Blizzard neglecting us so (except in Sunwell, that instance was the best thing to happen to raiding shamans)
These are obviously PvE healing suggestions, not PvP ones. Its been a long time since i seriously PvP'd (like season 1 early 2) but crit based mana regen is a great fix to mana regen in arena, which always drove me insane, after tide was burned (someone familiar with shamans would know to look for it and kill it asap, i know i do) you had to spam water shield and hope some hunter or lock is dumb enough to sick their pet on you. Also by making us crit-based our healing output is obviously increased by quite a bit, and Clease Spirit seems very nice as well, removing a poison, disease (will become very handy in arena vs. DKs) AND a curse, not OR.
