This has been an issue for a long time, and for new players one has got search almost every skill read the description until they find what they looking for. The skills in the categories they in right now makes no sense at all.
Here is one example:
Say I want to reduce some 'cap" needs to fit something else in, the obvious place to look is Engineering tree for saving on all things like ‘power grid’, ‘CPU’ and cap,
however if I go to navigation I find a skill for microwarpdrive that reduce usage by 5% per level. these types of skills should either be in a category of “CPU” Power grid & Cap under Engineering not navigation etc it has nothing to do with “high speed manoeuvring” or navigation in this case.
Call it whatever you want but at least put the skills in a relevant category. so one doesn’t have to search everywhere. ditto all the other skills in game.
CCP Its a question of reorganising the skills to a relevant category, based on what the skill does not the name of the skill which in a lot of cases is totally irrelevant to what the skill does.
