I have played wizards and fighters and clerics and paladins and druids and rangers for over 30 years. I have with all these characters been the one to shined and been the one to stand aside while someone else shone at many different levels. I have used all my spells and only a few in various encounters. I had a fighter tonight hit and do over 60 points of damage in one round (without a crit) and watched the wizard cast an 8th level spell and only do 48. Each class has its role and abilities and for the most part I find the core classes to have been well balanced. Its the supplemental classes that were often unbalancing and poorly designed. There is nothing to fix about the wizard in "5th edition" and there was nothing to fix about it in 4th edition.
