Agreed. Playing tactician, and it doesn't feel like I need to cheese anything at all. The "puzzle bosses" ARE fun, but as soon as you realise that if you play the puzzle correctly, the stats almost don't matter, it becomes too easy. Most bosses go down in one or two attempts.
One of the bosses (end of Act 2?) really scared me with the visuals, it was phase 2 so my resources were not full, and I thought I was in a fight for my life. Yet he failed to kill a single character and I just DPS'ed him down. It was a strange experience.
Part of the fun of playing DoS2 (at least the early - mid levels) was that you had to be smart about using multiple various tools - consumables, positioning, teleport cheesing, and it was satisfying. The odds face-on in tactician were never in my favour.
Yet in BG3 there is no point to think about builds, combos, and max out the tools that are available - they are never needed - and I would expect that to be the case on the highest difficulty.
