Talent Trees Are Garbage, and Here's Why.

I'm just going to use the arcane tree for mages as an example since i looked it up first.

Tier 1 Talents: All boring, Pushback resistance should be baseline, random small % buffs for talent point sinks. YAY!

Tier 2 Talents:
Arcane Potency is decent enough. Boring but is a little bit fun.
Arcane repulsion is interesting but cd is too long, but making it shorter would make it overpowered, should probably scrap that one.
Imp Missiles, mandatory talent sink
Imp blink fun spell that will only be used in pvp specs.

Tier 3:
Solid all around, with one pvp only talent in imp counterspell

Tier 4:
Imp poly is good, pvp only, then a random raid buff talent dump, then a kind of weird talent that isn't that interesting.

Tier 5: Slow and absorption are solid, I'm not a fan of talents that just reduce the cd of everything though, Arcane Flows is just a mandatory point sink.

Tier 6: Focus Magic is good, but kind of weird to have it this deep in a tree, imp mana gem might as well not exist.

31 pter: AP, good talent all around.

If you were to ask my opinion, just from this tree, only about 8 of the talents are well designed overall, and a large chunk of those are pvp talents. I don't consider mandatory point sinks like improved arcane missiles a well designed talent, neither are cd reductions or straight damage buffs. I thought the point of this new talent system was to get rid of passive point sinks that every min/maxer has to take.

Talents should open up new avenues and abilities, not make it so you can do 6% more damage with certain spells.
