If you'd want to do damage & be somewhat sturdy you'd simply use the bruiser set. Bruiser builds by definition are a mix of offense and defense. However, they're also supposed to be lesser tanks and lesser damage dealers than their non-hybrid counterparts. But because they get acces to both high-end tanking & high-end damage items you now end up in a situation where certain bruisers can both be as tanky as a tank and do as much damage as some of the more glass canon characters, which is bad design and makes the non-hybrid classes feel weak. Especially full-tanks feel weak because of this as the 10% more defense that they have cannot make up for the fact that they're only doing a fraction of the damage the bruisers are putting out.

It doesn't enforce a meta, it simply makes sure the different classes are actually that, different. A bruiser would still be sturdier than a class canon and deal more damage than a tank. But A class canon would deal MUCH more damage & a tank would be MUCH more tankier, as opposed to the small margins you have in life.
