That absolutely fine, I think it would be much better if everyone would just suggest to make classic slightly harder instead, since we have explorer mode as well. Definitely a LOT of people including me and my friends that would be really disappointed if you convinced larian to nerf tactician mode.
It is not "nerf" it is BALANCE, Tactician is not hard is just a cheese fest.
We haven't used any cheese so far and we are doing just fine. Please ask for them to make classic mode harder instead, there should always be a brutal difficulty because a ton of people prefer it like this. A boss should at least take a few tries is what I think, so does my friends.
