He's not hurting anyone's feelings, and I didn't say he was. But his view not posited as personal opinion, is it? It's stated as fact. Leave some room for disagreement.
For instance, your dominant tactic is not what I use, and I don't feel shortchanged. Does the game offer a scope for different playstyles? Sure it does. But there will always be assholes who want to make math out of every God damned thing. What's the optimal way to play? Are you kidding me, friend? 'But I can't beat PotD without tactical cheese! This tactic is the only way.' So what? One handful of sliver of a fragment of this niche genre of gaming wants the kind of balance that means every party/tactical combination is possibly game-beating. Another sees balance as an exercise in killing 'fun'. The bulk fall somewhere along that continuum, shrugging their shoulders. Who should the developer cater for? Did you play BG/BG2 because of the amazing tactical encounters? Was it killing Firkraag with 2x Greater Malisons and 1x Finger of Death that scratched your tactical flexibility itch?
Or summoning a hundred waves of cannon fodder for Sarevok to chase around, while your whole party pincushioned him to death? Was it your fighters/barbarians/rangers who were doing the bulk of the killing? Or was it in fact your wizard/sorcerer/cleric combos, wiping out packs of enemies before they even closed range?
Ultimately, friend, you're storming a teacup, and taking a shit on the best good faith effort (so far) to recreate something I value from my formative years. It's not the tactical brilliance of BG2 I wanted to see again. Why is our genre of choice infested by this sort of polaristic, zero-sum reductio ad absurdum? Yes, the combat system is less than ideal in some ways. Yes, it does present some problematic dynamics for people stuck in ADnD2/DnD3x thinking. No, you're not going to be able to run with a party of clerics who are better fighters than your best fighters, and casters on par with your most destructive (see: DnD 3rd Ed Clerics). No, PoE probably doesn't need a Tier system to compensate for incredible class imbalance. The sky isn't falling. PoE is really, really good times. Combat, warts and all. Long may it continue...
