[Mechanic] Won't be able to max Portal, is it a big deal?

Having level 8 Portal as opposed to level 10 Portal really isn't all that big of a deal. Most of the time I forget that I even have Portal on my mech and just play as normal, and when I do remember portal I end up recasting it every minute or two because there's no indication of when it's going to expire.

Just wait until Nexon inevitably gives everyone free SP resets again with their next revamp.
