Sadly it is a very popular opinion. Classes not being locked is one of the worst deccisions. This is why everything become so homogenious, and they keep adding rend and brittleness to every weapn and tree. Because they have no idea how to balance all weapons for every class to be vaible. Everything will end up feeling as a reskin in the end.
Crazy how it’s not a problem in V2, where almost all specials and elites are the same.
How you balance games with classes lock is that one class can deal with specific threats faster or consume less resources i.g. being more efficient than 2 or 3 combined. It doesn’t mean if vet netted run is doomed, it means that dealing with specific threat will eat more team hp, consumables, ammo, etc. It also provides coop gameplay cause your ogryn bodyguard probably would like to work with high damage squshy class in pair. It brings that feeling of you being a part of the team and doing something unique.
And if you don’t lock classes you balance gear - either with quipment weight or limit, so you can’t bring devastating melee and range with every character, or you can’t have a lot of heals, your team will do objectives slower, etc.
In DT you can have 2 plasma VoC vets without any consequences. Or just 4 ogryns, 4 ogryns is the most nobrainer thing, clear evidance - the more ogryns there the easier Orthus offensive on hard mode.
So emmm…make them not silent? Just like their V2 predecessor?
