In my opinion, We're at a point already past this discussion.

Meta builds already avoid investment in skill, and have no issues in terms of skill selection; more a skill variety one. I almost never end up building skill on my IC's, and in only one of them do I think about swapping my skills about pre fights- another option that hasn't really been brought up here, the skill slot limitation promotes a lot of metagaming. The stronger classes don't necessitate more skill due to having less skills, but skills that do more per slot.

Otherwise, your generally going to destiny into a class for more slots if its absolutely needed, though this is rarely a limitation in the unga class combinations. Mages and tome users have the easy option of spellbook being an effective 25 skill, allowing said classes to be at a significant stat advantage in cases where your trying to go stat for stat, and are already a very stat efficient class with their defensive scaling damage options.

In my opinion, a blanket increase of slots wouldn't be especially harmful, but should lead to further buffs to destinying and monoclassing classes, as this would be disincentivized otherwise, and few classes would derive much mechanical benefit from having the option to equip more skills, and at the very least make offer players more options to take in fights.

However, outside of a case by case fix, or a very awkward and specific boost to skill slots? There isn't any easy ways to 'remedy' this if you believe giving more slots across the board should be avoided.
