The problem is the demoman has about 6 or 7 different Demoknight weps whereas he only has about 3 Grenade launchers (which is what he was originally intended for)
some more Grenade launcher/sticky bomb launcher choices would be nice.
also more engi secondaries
all he has is Pistol, Wrangler and Short circuit.
ok so we have normal grenades. they bomb for a lot. good.
we have nitro fast grenades that do a lot more. good too.
we have weaker grenades but can be manipulated to deal a load more knock back than damage.
do you need any more grenade launchers? nop. you really have all you need right there
sticky launchers
default is good
so is scots, i prefer it in mvm.
there could probably be one more, maybe one that trades damage for something else, much like the loose cannon.
engi secondaries are fine. he is strong enough with a sentry and a shotgun, theres no use trying to buff an already busted as forget class. he is pretty much like playing two classes at the same time + a medic.
