52 skill points..

Okay, so my dervish has just reached the final skill trainer in NF.. and i have about 25-30 skills left to learn as far as just dervish goes, now - i have the platinum and the skill points to do it, but in your opinion is it worth it? Once all the missions are done how hard is it to continue gaining skill points? Im just reluctant to use them, but i would like all the skills - hah ^^

Depends on what you'll do afterwards... Normally in general there is plenty of xp around imo

If you plan on PvPing, it's always nice to have every skill unlocked. If not, only buy the ones you think you'll use.

For every class there's a few good skills and a lot of shitty ones. When you need a skill for a build, buy it. Don't just buy them because you don't have them, its unnecessary and a waste of money. Also, when you need a new skill make sure to check the Wiki page for it to see if its offered at any Hero Skills Trainers. Spending a Hero Skill Point is better than spending 1k.
