I completely agree with this post. I logged in today, excited to try the new patch. Over the course of one expedition I was downed 5 times because I pressed my potions at 1/2 health but they didn't go off. That single inconvenience drove me out of the game for the night and all the way to the forums to make sure someone was talking about it.
And on the dodge roll topic, dying to the fat enemy spawning a dozen enemies body blocking you in, is one of the worst experiences in this game. If you want to force the player to put a teleport on their skill bar or take the the point on the passive tree, you need to significantly buff the notable-node itself or all the nodes behind it. Even something like, "If you roll through an enemy, gain movement speed for X second(s)" or "If you roll through an enemy, reset your dash." would at least make the node or the nodes behind it DO something. At current, you've basically just made the game feel bad for no reason by default. Forcing players to seriously consider wasting 1-3 passive points just to roll the way you would expect to in 90% of the games on the market.
