I had put off tower grinding more in anticipation of Patch 3.04, but here's some more feedback, this time I tested all of the tier 3 classes:
1) Ranger's learn Rally Movement at 1, Certain Blow at 5, Sure Shot 10, (Overlaps with Lute, much better to promote Forde although his STR sucks) Bowbreaker 15. Could have been overlooked, but in patch 3.03 Rangers, and Nomad troopers certainly do not learn Canto.
2) Seems you cap of 60 health for Guardians wasn't working, I got Seth to 107 hp with Angelic Robes before promotion.
3) Angelic Robes add 10 hp, description still says 7 like the Vanilla game.
4) Tower floor two can have an enemy spawn in the top-right wall. It's 1 tile from the "floor" so it isn't stuck, but still a minor bug.
5) From more tower grinding, I learned the floor 3 Lord can be one of several units (promoted lord, cavalier, Halberder or even a monster) which will always lack weapons.
6) Rune Sword seems to be unable to crit, but the weapon stat and character stats show "0" instead of "---" crit chance.
7) Staff Savant skill doesn't work.
Specifically feedback for Tier 3s, it could be in some cases I didn't learn anything in grinding the T3s to 20 due to overlaps with previous skills.
1) I noticed High Priest and Blade Goddess actually lose 1 MOV on promotion, is this intended?
2) Guardian loses Swordfaire on promotion , gains no new skills.
3) Blade Goddess replaces Galeforce with Critical force (Also loses 1 MOV), It feels like a waste to promote for S ranks, Bows and Lancebreaker eventually. Lightweight and Seal Speed are underwhelming in comparison, to me.
4) General loses Expertise, learns no new skills.
5) Ranger loses Rally movement, learns no new skills.
6) High Magus learn Inspiration at 10, something that certainly overlaps with Sages from which they promote.
Druids, Vanguards and High Priests (mostly, aside from MOV and skill that doesn't work) I find to be great.
