This is perhaps the most wrong thing I have ever seen on this forum. Congratulations!
This is where Radec would come into place. Ratchet can barely dodge his level 1 (it hits whether you air dodge or roll 60% of the time.). Use that to your advantage.
Haven't really noticed an increase in Ratchets lately; I feel like they've always spammed the pistol.
I have noticed a lot more Dantes lately though. It's a shame they have no idea what they're doing though; spamming square with Dante will get you absolutely nowhere.
