The short:
Not good.
The long:
Here’s why, Summon familiar is not an amazing skill. It’s good, not amazing. Also, since you’re taking link 1, you’ll only have 5 links and not exploiting that by using summons/templeshooter is really gimping yourself for no other reason.
Also you are going to have extra skillpoints no matter what you do and putting more points into Salamion is a bad idea.
So you have a choice between maxing Salamion or maxing Summon. It’s pretty clear-cut from there.
As for endgame choice, since you’re running wiz3 link, I’d suggest going WL to squeeze out as much dps as possible and still keep your QCast attribute relevant seeing as summons dont scale off MATK but your INT.
You could run Sorc3 but since I’m not a sorc3 I cant give you a complete answer, might want to wait for a Sorc 3 to answer.
Summary:
You’ll have extra skillpoints.
Maxing salamion is a bad idea.
Quickcast + Warlock = omgwtfbbq everything just died.
As a sidenote, I have almost 0 downtime on my Sorc/FF so if you ran link sorc2 warlock you really shouldnt have a problem with SP. However, this means you’ll probably spend a LOT on Lv.10 SP pots. Not willing to? You’ll probably refill your sp bar in under 45s with cat buff anyway and even that is undervaluing it. ALSO, having summoning doesnt mean you have to have your summon out 24/7.
