i believe and hope that Cleric spells still scale with Wisdom even when Wizard learns them
Nope
Wizards use their regular spellcasting ability which is intelligence. Also, patch 7 introduced the proficient scribe ability for wizards. Scrolls cost half off to scribe if they're part of your school of magic. An evocation wizard can learn Healing Word, Cure Wounds, Prayer of Healing and Guiding Bolt for 125 gold.
Keep in mind, you can prepare spells at leisure outside combat. Healing spells can be great in a bind, and having a backup healer never hurt. Or you can be proactive and have both wizard and cleric chaincast Healing Words on the barbarian while sipping martini in the rafters.
I'm not saying it's not fun. It makes wizards powerful in a unique way. Building up Gale's toolbox and figuring out how best to use it was part of what I enjoyed about my patch 7 run. I was also relieved not to come across a Bless scroll. I rate it so highly that it limits the decision space.
I've posted plenty on this topic, but I may be slowly changing my mind. At this point, I'd rather see something unique added to the cleric than see this ability removed from the wizard.
