TBH, I did and do not like this "vote a skilltree" thing.
Especially a lot of stuff promoted in "summoning mastery" for example is extremely meta, and actually a must even without that "goal". For example the single->multiple summons trait/perk/spell, that already was a insufficiency in D:OS no other path had. There was no "you can only cast 1 fire spell each round" or something similar.
So making that optional was, imho, actually a bad decision. Unless it meant to be done anyway, which on the other hand, would make the choice pointless. So yeah... not a good idea, imho.
That's btw why I voted for most interest in the modding tools. Already wanted to dig into it with the EE but... well, ya know, quite some shortage there reagrding that. ^^
