There was no option to state this in the surveys, so I'm posting this here.
Consider an enhancement which is getting additional types of bonuses at higher ranks (eg. Halfling Companion, Halfling Stealthy).
You don't see these benefits unless you actually spend at least 2 points on the ability. It would be nice to have a preview of the higher ranks in the tooltip, e.g.:
"This bonus improves to +2/+3 Hide and Move Silently. At rank 3, throw attacks you perform from stealth deal additionally +1[W] damage."
This is a general issue for any enhancement (or epic destiny ability) with multiple ranks, but for these enhancements, the downside is that the abilities look worse than they actually are - it looks like the bonus is 'hiding' in rank 3, not wanting to be discovered.
