Is it better in tactical mode?
I use tactical mode regularly, so probably. I play as a warrior, so no magic coming from me, I only have Cassandra, Solas and Varric to deal with, I spread my teammates out on the field to separate the enemy a bit so they're easier to manage, and I always go for mages and archers first. Also, I'm playing on my tv, not a monitor, so that may make it easier for me to deal with magic stuff too. There are color effects, but when you're actually playing, and you're focused on what you're doing, I don't think you're inclined to care.
