Also I don't think the devs will be able to avoid minmaxings regardless of utility TF or not ^^;
Ever since the creation of non-linear gameplay, players have always tried to figure out how to break the game in their favor. The infamous "stealth archer" of Skyrim comes to mind.
I think that kind of presumes that min-maxing is a bad thing. It's a play-style which essentially requires some level of theory-crafting and meta-gaming, which defeats the purpose of just playing for fun. Should that result in it not being possible? Depends on the developers' wishes, as well as what you (the player) want to do.
Also, as WolframL pointed out, the CoC2 developers are developing the game in parallel with us playing the game (testing it), so that results in an entire community of people being able to provide feedback to the team (not to mention a community of people who are invested in the game).
This contrasts the way Bethesda developed Skyrim, which was released upon completion (and not patched / fine-tuned much), and was only tested by internal testers who probably did not have the same amount of raw numbers that this community does.
That and the Skyrim community found countless bugs / glitches in the game which the testing team seemingly missed, sort of emphasizing that people who are invested in the game (wanting to play for fun) are usually more thorough than those who have to do so for their job.
In reference to the above, it then indicates that if there were any instances of something being potentially "broken" or "OP" the CoC2 staff would have sufficient valuable feedback to sufficiently assess the situation, as well as already be developing instead of post-patching a completed game.
So, in conclusion, would it matter if there was a "stealth archer" Skyrim-esque character archetype in CoC2? That would depend on whether you wanted to play that way, and whether the development team felt it was alright to have such a viable build. As mentioned before, this comes down to the different styles of development between these two games.
