I can't stress this enough but metas that revolve around speed are just plain annoying. One extra point of speed on a certain character can basically decide the battle before it even started.
The problem is you feel helpless and don't know what to do because adding gear doesn't solve the issue when your issue is mods. Even more so when you've farmed an endless amount of mods and every time you upgrade speed doesn't go up. You spend crystals, farm more mods, get nothing, then you must wait another 24 hours for the refreshes to reset and go again, meanwhile day after day you lose battles because you're one speed slower than the opponent and day after day you can't get a mod to match theirs.
