ok so i ll explain that

there will be a skill update.
that means you will have only 240 skill lvl not 360 anymore!
and the masterys fire/ice/light will be all one big mastery instead of 3.
and force will be 1 mastery and every single weapon will be 1 mastery.
so with 240 points you are able to max 2 masterys that means you can upp:
2x a weapon mastery, the (fire/ice/light) and the force mastery, 1 weapon + force, or 1 weapon + (fire/ice/light)
so in this case you have to go for Weapon (heuskal) + (fire/ice/light).
but atm you go for heuskal/fire/ice and then you can lvup the light mastery after the update ^^
