why? commando doesnt have anything near the lolcover mechanic... cast times on sniper are fine because u cant be interrupted and u have CC immunity on a button if you need to resist incoming crap.
commando has 0 of theses tools and bioware still made it with cast times, retarded to say the least.
Because no spammable main attack should be instant cast. It would make commando dominate the other ranged classes.
