After watching the video I want to say two things:
- You will get flooded with magic items.
Even in EA its easy to have a special magic item (not just generic +1 stuff) in every slot. And the video says you will get much more later in the game.
Personally I do not like that. I liked BG1 where it takes some time to find a magic weapon at all and unique magic stuff is very rare or expensive.
BG2 had much more but it still felt fine. ToB went way too far.
If you find special stuff around every corner it stops feeling special.
- He says that profiencies are very importent because lots of equipment (e.g. helmets and shoes) need profiency.
My opinion:
- Most players who play on normal or easy don´t need to care. You get flooded with stuff so you surely find something useful for every char.
- Races with profiencies (dwarf, gith) will become popular, especially for classes without armor and especially now that stat bonusses seem to be no longer connected to race.
- Players who want to solo the game or play the hardest difficulty will do crazy stuff to become gods. (random hypothetical example: My gith sorc absolutely needs heavy armor profiency. Because heavy helmet x together with greatsword y and buff z will double my fireball damage and they ignore resistences so I can blast everything with 3 fireballs in a round before the enemy can do anything)
