I know flamenades are a problem, but you are forced to get them as a garrison clearing tool.
If that is delayed (too) much, okw can get locked-down on certain maps.
Either make the nade only throwable on garrisons (ugly fix) or just get rid of it all together and make flamethrower non-doc on sturms.
Or just give the flamenade to Sturms. It wouldn’t be overly strong as a combat tool to sturms aside from garrison clearing since cover doesn’t matter at the range where they can fight anyway so it’d be an ok fix without heaping even more onto sturms (people seem to complain they have to juggle too many roles and having flamers means no sweepers and no schrecks).
