Graphically: 100% better, am glad the preview looks weren't the end. Rightfully gnomes now.
Enhancements: interesting enough to bait some people---looking like best wizards. Looking like good mechanics, if you don't want to be halfling and get low ips. The competence bonuses to threat aren't crazy good but might please some people.
You guys need to add 6 more illusion spells for that to be a viable school though. You are not in touch with that spell focus and how it operates. There are currently 3 illusion spells including the prismatic SLA that are of use. One of them causes people's eyes to bleed. An overhaul of illusion as a school would really help sell gnomes and give focus to their addition to the game. This is the best way to broaden the game horizontally and would be a welcome addition.
Lookin forward to fighter update!
