I havent played xul or played against one that took q 13 but
Three things id suggest about the wr of his 13 q to take into consideration: 1. It doesnt require that he's in melee range, 2. It's fire and forget, and 3. It provides zoning.
The use of the lvl 13 w talent is to proc more heals and to ensure the cdr talent, swiping your opponent more doesnt really do much imo. Since it procs on everything it makes him the fastest infernal shrines clearer. I have no idea whether the q 13 competes with it, but if it did id prob take it instead.
W/r/t w 13 i feel like it's a kind of malthaelish decision; your main consideration is whether you can outsustain in a fight. It's not a bad gameplan for xul who can drop a lot of important cds before he goes into melee range and after his cds are done; it's very valuable to have him be a target in a fight instead of standing on the outside waiting to get q value again. At the same time, this is a very team dependent build because the only thing xul has to keep ppl melee is his e and ult, and that's comp dependent and in general unreliable (plenty of ways for the cast to get around both). He needs ppl to cc the ppl he wants to hit to get value out of this build.
Ive never seen q 13 but one of the more important things to consider is whether it's dodgeable or not. The winrate at least trends towards showing that ppl arent great at it, but that's less relevant than the idea that ppl are able or unable to if you are talking about talents and the way xul does stuff. If his stuff is consistantly dodgeable with practice then it's main value is for clear(?), zoning, and burst damage on cc'd targets (do they all hit on a target that's not moving?). That's not bad at all, plus he relies less on being in melee range. But there are def comps where xul being in the shit is pretty important and w certainly holds more value in those instances.
Not really a clear cut pick one way or the other imo.
