Mage
Tier 1 - Is this a trolling attempt? Every other slot on other classes affects dps or healing or survivability. Neither Fireworks nor Light are relavent to combat. Functionally, mage only has 3 tiers of talents. This would be a fun feature of the base spell that wouldn’t affect class balance at all, but I hope you reconsider this tier and replace it with anything else.
Selfish Streak / Shared Streak - This is good. Reward for learning to cast correctly. A buff I can keep rolling in a fight. Just have to decide between helping my group (assuming the range is high enough to reach the ranger at max range, and melee dps at the boss), or a guarnteed dps boost to myself.
Lend a Hand - Great for everyone who isn’t Decoy. Now we can start chain casting without doing dps to the floor and ceiling. This and static charge are good. I’ve been wondering why mages even have a second hand. Now I won’t be shoving the other controller in my pocket!
Static Charge - You have my interest. Range? Aoe? Faster than charging an Ult? Depends on how much dps this adds. Obvious choice for Decoy.
Elemental Affinity - I can see a few different rotations that make use of these. This will totally wreck my current runesets, but it may be worth it. This seems heavy for single target over changing targets.
True Affliction - Dots are dps on single target, so good for boss fight. Aoe dots are good for trash pulls and farming reagents from low mobs. I can use this. This is good.
Musk -
Improved Renew - healing buff. Good for solo, great for groups.
Improved Poison - I need to test again. What was the length of poison vs the cooldown of the orb? This may be a buff if length <= cd + 2.
Improved Lifewell - Great! That was hard to get everyone to stand in and still dps bc of body collisions. Longer duration makes it even better. We make our stand here!
Speedy - Eh. If you happen to drop the turret exactly the number of seconds before the last mob in the group dies, and if everyone is close by ( sry rangers), then you get to move faster to the next pull. Solid meh. Maybe this is a pvp talent?
Renewed Synergy - Tank healing buff. Self healing buff. Frees the renew orb to throw at second area.
Totall Recall - Good for being on the move. Not resetting the lifetime kinda hurts. Not sure I’d ever take this over the improved healing. Solo play is too slow to need it, groups would benifit from the healing more.
Light’s blessing - Makes Cure a 25% aoe. Nice. Very nice.
Empowered Turret - This feels like a solo talent. It depends on the strength of those new effects. They would have to be very strong to make this a better choice than lights blessing.
The changes to the ranger talents look really good. I’m excited to try out all of these.
