This is true, but DA:O and DA:A had mods that allowed you to turn those things off. Well, that AND even if you had it on it was not as bright and obtrusive as in DA:I. I like when a game is colorful and gives you all the information you need visually, but it has to be done well. Three orbiting shields is a bit too much, as are bright purple glowing arrows, and a shatter effect for shield bash that is a foot thick.
EAware has lost all art of subtlety.
Mods aren't a huge plus when only a third of the available platforms support them. But I wholeheartedly disagree about them being less intrusive in Origins and Awakening. Those effects were apparent in dialogue. It really does not get much worse than that, because it's one thing to see those effects during combat, but it's another when your character is standing there talking to someone, all the while having some cascading stream of color engulfing your entire group, or worse, making some repetitive booming noise. Like, imagine if DA2's rock armor stayed active even while Hawke was talking to someone. This is actually the case with Wynne, since rock armor is just a steady stream of gravel flowing down her body, which stays active even in dialogue out in "danger" areas. It'd be ridiculous. But let's not forget some of the other glowing weirdness in Awakening. Spirit Warrior basically has the medieval equivalent of the Sentinel's tech armor. You literally spawn a glowing force field of extra armor, and this is around a regular warrior who should have no latent magical ability whatsoever. It at least deactivates when combat is over.
This is seldom mentioned, but I dislike the way enchanted weapons just blaze with fire or electricity while strapped to your PC or party member's back. I very much prefer that it only be active when engaged in combat, same as the other various effects.
I never really had a problem with the glowing arrow. It only occurs during explosive shot, and you could easily attribute that to whatever alchemical alteration was made to that arrow that makes it explode.
Subtlety was never a thing when it came to DA's combat. Heck, for all the guff people give DA2, you had to actually check the sustained abilities on the wheel to be sure that the ones you wanted were active. Hawke didn't constantly glow green when a duelist ability was activated.
