I think it is a good idea to reduce range for bows, it would just feel silly, if you would need to move 2-3 screens and 2-3 rounds in order to hit the enemy in each fights.(...)
Realistic ranges are not for TB.
Do you realize that there are a thing called map design and that 600 feet range longbow is something situational in most dungeon crawler games? That there are spells like Dimension Door or Haste to help you close the gap?
Wizard - a guy who turns invisible(...) creates food
You are so bias towars "muh wizards op" that you ignore that create food is a CLERIC spell, on 3.5e and on 5e.
https://www.d20srd.org/srd/spells/createFoodAndWater.htmhttps://roll20.net/compendium/dnd5e/Create%20Food%20and%20Water#contentYou again ignored divine casters in your comment.
In general on 3.5e / pathfinder, Prepared Divine caster > Spontaneous divine(Oracle for eg) > Prepared Arcane caster > Spontaneous Arcane > Martial. And wizards needs scrolls, otherwise they can't learn the spells and scrolls are expensive. Finger of Death costs 2.5k gold(not sure), imagine learning ALL spells of the same level.
