The respec screen can be very frustrating when you're trying to decrease certain lower level skills to allow you to increase higher skills. The increase/decrease pts arrows (up/down) enable even when they're not usable. You have to go and click the remove pts button on a skill for it to tell you it can't be used because of a dependency. This is annoying since you have to try all of them before finding out which one you can decrease. It would help if it never enables unless it's usable. The dependencies can be displayed on tooltip or on selecting the skill if necessary.
Alternately, this would be unnecessary to start with if the skill level quotas are removed or at least relaxed a bit
i.e. so you aren't forced to lose X pts on LT skill before you can select commander skill etc... This would make many players much happier.
