I hear many people say that frost mage burst is not too high or that competent players can simply counter it with ease. Well I just recently stumbled upon this example that highlights how deep freeze / frostbomb burst is, in my eyes, pretty overpowered: Top players in 3s get completely overwhelmed by the burst put out by a single Frostmage who is running...with two healers
Here is the full 3 hours of streaming games with some more games that Reckful, Nadagast, and Toez play against the Double healer + frostmage setup. If you have the time, it would be prudent to watch a few other games they played against with other teams before jumping to conclusions.
Forward to around 1hour 30 mins to see the matches against the rank one double healer + frostmage setup.
Make sure to keep an eye on Nada's recount.
The burst against Toez might could partially be an issue with resto shamans being too "zergable" (cough totems while silenced), however it looks to me like frost mages simply have more burst in opportune times (and more pvp damage in general) when you compare it with any other game from the 3 hours of footage. Another factor is that Jahmilli has two healers so maybe he overextends and that allows greater damage output. Even with these factors taken into account, I feel that the frequency and magnitude of frostmage burst exhibited here is far too much.
I just wanted to get this out there that the frostmage "nerfs" seem to have done nothing. The pvp on-use trinket change possibly made them even better due to lining up with deep freeze. Frostbomb seems to be the main issue and it hasn't been properly addressed by reducing the burst potential associated with it on the main target.
This is my humble view on the situation. Tell me what you think. Please be constructive and provide support for any argument made.
Here is their team, which is currently at Rank 1 in the best US battlegroup:
