Regarding the latest Arcane changes (having tested several different builds and done a couple dungeons):
Overall, these changes are good, and the newest talents introduced today are (mostly) on the right track. I am having a lot of fun playing Arcane now, especially AoE-wise. However, the talent tree is still very bloated and disorganised, (both of) which this build exacerbated, unfortunately. Moreover, it really needs pruning and several talent redesigns. If these issues are corrected, then Arcane will be in an excellent spot for TTW (note that the following adhere to no particular order):
Talents
1.) I am pleased that Arcane Orb is now baseline, which frees up an additional point. The irony, though, is that the incentive to select the new talent Resonating Orbs is high enough, so that we effectively do not gain the extra point at all. Flat damage increase talents are boring and unnecessary in most cases, and Resonating Orbs is an egregious example of one. Please just remove it.
2.) On the subject of flat damage increase talents, I am truly perplexed as to why Crackling Energy and Improved Arcane Missiles not only remain in the tree, but were also nerfed this week. I understand that the affected spells might otherwise be too powerful if the bonus stays at 10%, but this is really not the issue; rather, the problem is that these talents should NOT exist under any circumstances. Just taking these out would very much improve the talent tree bloat situation. Now nerfed, they serve even less purpose than before.
3.) Arcane Tempo is still as dead as before. At this point in development it should just be removed.
4.) Dematerialize is brilliant: Arcane has long, long needed a DoT and this fulfills that need perfectly. Please keep it but buff its damage. As for Energy Reconstitution, this is likewise superb (though it needs to do more damage and proc more often; I would also like to have some control over it). Big Brained is OK at best; I do not care for talents like this and would prefer to see it pruned.
5.) Static Cloud is great: Arcane Explosion finally feels meaningful to press. My only suggestion is to make the talent also increase Arcane Explosion’s casting speed by a small amount with each successive cast, as AE casts are too slow at the moment.
6.) While I understand the intent, High Voltage is nonetheless niche and should be redesigned.
7.) Prodigious Savant really needs to be one point or changed: it’s lacklustre and extremely dry.
8.) Leydrinker is still in need of a buff, and Nether Munitions is both underpowered and poorly designed: it occurs after the burst window. Please replace it with something much more powerful and interesting. Talents of this kind are boring and subpar.
9.) Magi’s Spark now functions correctly and deals good damage. In my opinion, though, it would be best to buff it more, given its capstone position and its being tied to a 45 sec CD.
10.) If the utility nodes are here to stay (even though they shouldn’t), then at least allow Chrono Shift to be baseline, so that we have yet another much needed point.
11.) PLEASE, PLEASE just make one of the Arcane Barrage nodes baseline. There is simply no point in having three separate talents.
12.) Finally, Evocation should be baseline and Siphon Storm removed. The latter’s presence is stifling build diversity, and the former is so fundamental to Arcane that it has no business being a talent, especially not so far down in the tree.
Spellslinger
1.) Unerring Proficiency needs a buff: increase the stack count and make reaching the maximum stacks reset the CD on Supernova.
TLDR: consider the above suggestions and prune unnecessary, flat talents (straight damage increases, especially) wherever possible. It’s disappointing to have to pass up particularly fun options because I have to pick certain arid, but mandatory, talents. Even with this new build I still feel starved for points.
