Well im only telling you whats happening in our games, not theory crafting.
This. Seeing a difference in gaming experiences is good to have for perspective.
Here, in my group, my Hadross have so far gone undefeated (Current list: Ooroth leading Bannerman with 6 deepmen and Friar with 7 gutters, 2 sharks, 2 crabs, Ilva, Oracle, and 2 callers). We got all 5 factions but my most regular opponents are usually either Shael Han or Teknes. I sorta luck out there because both of them tend to use abilities that require close proximity or base contact within their formations in order to work and that helps my own strength of Will debuffs/attacks and the threat of the oracle nuke.
Still, I'm happy with my Hadross's streak so far as it's at least felt fairly close and has left me with wins against my friends that I don't feel bad about. Most of my games do tend to be close, but I am usually able to just out-attrition my opponents whenever they make a concerted effort to block me from my objectives, which is basically what I force them into with objective placement because I know I can win those fights more often than not.
Currently, my friends rarely bother trying to rinse off Resonance since it's usually easy to anticipate and counter.
When most of the opposing force is already Resonate (usually by early round 2 after engaging), I try to give my specialists priority in the activation queue, using their ranged attacks to hopefully pick off an opposing leader/specialist or two before they get around to activating. Then, if an enemy group does try to rinse off resonate, I'll activate Bannerman or the Gutters immediately afterwards to re-resonate all of them fairly reliably when needed. My Oracle nuke tends to either be either the first or last activation in my turn (or, preferably, the last and then the first) because of how that works out.
What I think tends to be more of an issue in our games, and should maybe be the subject of another thread, is the perceived importance of having access to ranged attacks as many of our games usually feature a bit of a shoot-out between leaders/specialists over the line of infantry between them. Because of that, I'm also not really a fan that minis of the same height don't block LoF for each other.
