I think we should just take a step back and look at the bigger picture. This game isn't necessarily made "for us", with our optimal enjoyment in mind. We're some of the most experienced DOS players out there, and what we think are the best solutions (from our point of view) aren't necessarily the most optimal or intuitive for the main playerbase. Maybe Teleport is at a good level right now, and the OPness of it can be mitigated by other means, for example through a harder difficulty setting? Perhaps there are other ways to make it weaker, such as more ways to make oneself immune to certain types of spells (e.g Aero immunity, Earth immunity / resistance..)
I am on the boat with you for this. When I first came to these forums I wanted to share my experiences soloing the game because I was slightly bewildered that it was even possible. The new patch came out and I overreacted a bit to the Polymorph kit especially, from the perspective of someone that felt it was already too easy to solo the game with the skills in existence. I've come to accept (a bit optimistically) that my complaints in regards to some of the skills in this game will probably mean nothing once Tactician comes out or even late-game in Classic mode.
Teleport is strong, but I've always accepted it as a normal mechanic of the game. The only mechanics that make me uncomfortable involve cooldown resets and invisibility, but that's okay, too.
At this point, the only thing I
passionately think Larian needs to address is the Sneak mechanic, with the solution lying squarely in teaching the AI how to properly deal with it. If this AI rework is not possible, freezing cooldowns while invis is an unpopular suggestion I made in another thread, but it seems like an easy solution to me. Maybe just freeze them during Sneak, not the actual invis skills. I don't know.
The Armor/CC system as it stands, though theoretically it could be improved via some of the great suggestions we've seen, can probably be balanced through a reworking of the numbers, so I wouldn't be disappointed if they didn't change it radically.
