I hated those days so much. I love a good gish but not cover up for shitty forced resource management.

"oh boy, I played a fantasy game so I can be someone that can use magic and think about all the neat ways to use it and have an escapist power fantasy ... except that I'll arbitrarily just run out of magic so I can't play my concept anymore until later. Great. Thats exactly what I wanted. Thanks D&D." I'm so glad when a group is open to another system.

-edit- to clarify, I'm just saying I don't care for that style of play. I hope you find people to play that kind of game with and have a good time. Just at a different table than mine ;)
