they still pure,have they style and story,i know they weak than subclass many and I can't use they do hardest thing,but I main weakest class 3 year so I can hold 3 or 6 month
Definitely a yes. I made my alts because I wanted to play the different classes, and I still do. It would get really boring if they were all using each other's skill lines. Did I spend time training and learning how to play those classes so I could pick-and-mix them later? No. I want different characters, regardless of how the devs insist on "balancing" them to make subclassing work.
If I did want to subclass, I'd limit it to my arcanist, because I only made her for guild trial runs. She bores me, so she's the only char where I'd consider it an improvement to subclass her away from her base class. But I still wouldn't play her regularly, so it seems silly spending time training her subclass skills
For me playing an alt was always about playing a different character with its own theme. I wouldn't respec my main into 12 different builds just because I can.
