I'm with Luccheno on this one.
Both sides make valid points here, but until you have a chance to see (and even try), I find it hard to lock into an anti-mouse stance with any solidarity. Plenty of games pull it off just fine.
I haven't played League of Legends in years due to toxicity in the community (at least back when I quit it), but I found many of those matches to be incredibly intense - equally if not more so, than the SMITE matches I play today. On the other hand, I don't feel near the intensity in DoTA 2 as I did in League of Legends shrug
For me I'm open to whatever movement the developers feel best, and will form my opinion when I can see it in action.
