I was just fooling around with the game again in these days and once I reached level 5 again and got through a couple of battles I found myself thinking "I can't believe this game almost shipped without the Interrupt/Reaction system".
It's even weirder to think that at some point there were users on this very same forum arguing AGAINST its addition.
I feel like it adds so much to the quality of the engagements and that some classes would be basically crippled by its absence.
I doubt I'll ever get tired of activating a Counterspell at the right moment, for instance. And my hope is to see the whole system expanded with the missing spells and abilties.
Admittedly a thread that doesn't have much going for it, but there was no other one where sharing this realization was particularly pertinent.
