Not really.

- Presence of mind is already more powerful than lightspeed, why add a dmg penalty to lightspeed when AST DPS already lags behind WHM (even taking into account the cards in some cases)?
- 20% bole might be very powerful, especially when enhanced, but isn't as reliable as a tank CD since it won't always be up at a critical time.
- Increasing the range of CU just means it'll be more flexible to use, but the main weakness (channeling) still exists.
- Switching sects mid combat does seem OP at first, but when you really think about it there's no reason to switch sects even mid combat if you're a diurnal AST paired with a SCH, since your shields will just override each other. Therefore, switching sects mid combat would be more of a niche for a noct AST paired with a WHM and will bring it closer to SCH in power.
