O&S, Capra Demon are unavoidable and cannot be backstabbed/riptosed. How many people have had trouble with those? Plus melee are the ones that are having the most problems with multiple enemies.
Look, if you can spend most of your time in the game fighting only one enemy or setting up the situation for you to do that, then suddenly you force the players to fight multiple enemies and having them to be forced to learn how to lock/unlock and handle the camera at the same time, obviously players will hit a brick wall. It's not a gradual learning curve but a sudden jump. Yes, people can eventually learn how to do it, but you can't argue it's a good game design.
what do you mean by lock/unlocking? you know you can just flick left and right and select targets, right.. right? Although for huge weapons like the
going unlocked is worth practising.
both those fights you've mentioned are easily handled by blocking, dodging, having patience, and using the environment to your advantage. Capra is all about the first five seconds. He can be blocked or dodge rolled fairly easily. As long as you don't roll into a dog, and reach the foot of the stairs, you've won the fight. O&S is about using the environment to keep them aligned but separated, and they both involve having some awareness of what's going around you. I'm not allowed to argue that's good design? I think it is. Summon help if it's an issue - that's one supplied mechanism for dealing with it.
btw i do know about melee and multiple enemies, would you believe. you have a stack of options depending on your choice of weapon. unless you are relying on just one weapon in which case, diversify. Pyro is also available to everybody regardless of build. (as a melee build you should at the very least be considering
, so if you're having a tough time why not add a fireball or two?)
Frankly I don't really know what you want. The game gives you options, it's up to you to use them.
