I'm extremely frustrated with this system and believe it was quite poorly put together.

I can understand the reason for capping the amount of skill you can put into the classes, it generates some flavour because people are forced to make choices, and therefore it fosters community. FFXI did this for crafting and it worked well, I'm sure this is FFXIV's version to achieve a similar result.

The issue I have is not that you are limited in the number of classes you can have, but that the cap is 300 pts. This is stupid because you can't even have 3 classes at cap due to being unable to drive your desynthesis skill to lvl 0. This means the best you can be is having two skills at 100, and one at 95 (which means for those fancy items you will never reach 100% success rate on that 95 skill class). SE, I implore you... either raise the cap to 305 pts, or allow us to drop the lvl 1 skill for the classes we don't care for. What you've given us now makes absolutely no sense.
