Pellovleymight be interesting if each class were to switch at different speeds by default, with the heavy taking longer than average and the medic faster, idk. I dont think adding draw time as a factor will matter in most cases anyway, but it could make for more interesting variety
like the switch speed on the CZ in CS is one of the biggest drawbacks to the weapon. It'd be interesting to see a similar weapon in tf2 I guess. This could in general be a good way to discourage use of weapons that are kind of broken but not necessarily fixable with other stat tweaks. A longer draw/switch time on the Loose cannon might reinforce the shittiness of it as a PDW for example
also yeah pocket just feels so much better now
