Ive been a frost mage since MoP and have really enjoyed it. Ive always love the machine gun style build that was a staple of the spec. When Glacial spike was introduced in Legion, it was a cool idea. Thematically, it was fun and seeing a big number as a frost mage was cool. The first time it was truelly a contender for being meta was in BFA with in the Eternal Palace and with corruptions. I dont really remember where it was at in Shadowlands but not aure if it was all that great. It had its hayday in Dragonflight though and has been “meta” ever since. I know the mages are split on whether they like it or not and I fall into the dislike side of that argument. I tolerated it in DF and found ways to be viable with out it the other times (mage discord needs to grab a dictionary to learn what the definition of Viable is and means).
With having hero specs, I think this a good chance that both worlds can be satisfied. At the moment, frostfire is best for glacial spike build and I have found success with a spellslinger machine gun build. This could be a great opportunity to tune the two different builds in a way that doesnt cause much friction between the two and gives options to players. This post wouldn’t be worth anything if I just complained so my solution is two parts. Buff icicles for spellsligers and buf mastery for frostfie.
The buff to icicles is to target the passive damage that goes unnoticed but deals a reliable amount of damage. The quick pace of the machine gun build leaves little room to add more spells to improve your damage so it can play into the frozen turret where you position yourself well and unload on your target with a decent amount of freedom of movent since you have a lot of instant cast spells all of the extra frozen orbs you get help with keeping the procs flowing. I dont have corrisponding buff for arcane since it is spell related.
Glacial spike scales off of mastery and Int but its not a great idea to mess with Int. What made GS so powerful in previous expansion was its interaction with mastery with the mastery corruptions and necklace traits. With mastery being a decent part in fire mages as well it would benefit that spec too. Adding a mastery proc whenever Icy Veins is “casted” would give a satisfying power boost that not only would feel good seeing bigger numbers but would help excel GS mages at snap priority.
Just my thoughts, hope a dev might see this and let us re-enjoy our machine gun playstyle again. These would be a quick change that could make the spec better for everyone.
