Meteor without the proper aspects and the Adept Glyph is going to feel terrible for sure. A fully tailored Meteor build works smoothly but is of course miles behind the meta builds.
There are two fundamental problems which destroy build diversity for Sorcerers: (1) the inability to apply the Vulnerable status effect without using Frost Nova or Ice Shards, and (2) the ridiculous squishiness of Sorcerers which mandates the use of ALL 4 defensive skills for survival.
This means that all but one of your skill slots are locked as are virtually all of your offensive aspect slots because of the various aspects focused on the interactions between spamming cooldowns and having a barrier up. The only choice you get is on what your main spammable ability will be and it’s not really a choice there either because if you don’t take Ice Shards or Arc Lash you’re already severely gimping yourself.
Of course this only matters if you’re pushing higher tier nightmare dungeons. As things are right now, if you don’t want to play a super restrictive meta build you have to resign yourself to not pushing NMDs. Personally, that doesn’t bother me because if I can’t play a build I enjoy I might as well not be playing the game at all and pushing super high NMDs is neither fun nor rewarding atm so it’s a no brainer.
Hopefully all of this will change once we move on from what is basically a glorified Beta test of the game but that will likely take a very long time. In the meantime it is what it is.
