Hello Blizzard,
based on the current data from WCL:
→ Arcane-Mages have over 3000 DPS-Parses in sunken temple and they still doesn’t hit the 400 dps mark.
For comparsion, the next best DD will be the Shadowpriest with 613 dps. This spec which you add to the game is unplayable and Blizzard killed it with the last living flame patch.
I miss the Arcane-Mage buff in the 16th april patch!
Here are some ideas for better Arcane-Mages without making them to strong:
→ Living flame should spawn under the Boss and not under the Mage.
→ The Duration of Living Flame should be 20 sec if living flame starts at the Mage otherwise it wont be usefull. If it deals to mutch Damage adjust the Values!
→ Decrease the manacosts of arcan blast stacks from 175% to 125% and incease the damage buff from 15% to 20% or decrease the casttime from 2.5 to 2.0.
→ Rework arcane surge! This spell is only useable in PvP situations to one hit people. Realy funny stuff! Delete this dumb spell and make it playable in PvE situations, too. It should deal more Damage if you have LESS mana.
→ change Temporal Anomaly and make it available to the entire Raid instead of your own group. Otherwise you can adjust the value to 500 and let it buff all 3 sec or let it move faster after each shield that has been given.
→ Increase the duration of Mass Regeneration from 15 sec to 20 sec and Regeneration from 30 sec to 45 sec.
→ Add a Recipe: Elixir of Greater Arcanepower like Recipe: Elixir of Greater Firepower.
This are some of my ideas to fix this broken spec. I do not recommand to add it all.
