I have to say I'm disappointed by the pooling of a couple of actions/functions to one key/mouse button. While in some cases it seems to make sense (like 'Run/Sprint/Canter/Gallop;Swim Fast;Accelerate Boat' or 'Surface/Climb/Jump/[Hold] Roll') I can't help being left puzzled as to why 'Quick Access Item/Crossbow' and 'Witcher Senses;Parry/Counterattack' have been pooled together (default 'Middle Mouse' and 'Right Mouse' respectively).
One could argue that this also makes (some) sense, since there's apparently some sort of combat/non-combat state checking going on (meaning if in combat 'Right Mouse' would trigger 'Parry/Counterattack' while out of combat 'Right Mouse' would trigger 'Witcher Senses', I guess?) but it would have been real nice if you could alternatively bind some of those pooled actions/functions separately to individual keys (keyboards actually have quite a lot of these, you know) and not make it look like you're in for another one of those shoddy PC ports (control-wise, at least), where
one button does everything.
