No daily caps, but no gains between the times of RoT. However if you work all 6 or 7 skills, its not bad.
Also the use of SoA, you can log in, gain .2-.5 in a skill, log out. Wait timer out, and log in, gain and log out. With this method you can get a lot of skill points in a short amount of time. THe SoAs only last for 15 mins of time, so assume you have about 10s eaten up per log (there is a delay to log in and out, and do the macro) But its quiet easy to get 10 points off an SoA. I have done it many times. This of course doesnt work well with skills that put you in combat, as you would have to wait the log out timer. And things like taming is hard, unless you have someone helping you, bringing you pre-tames. Though its possible without, just not as viable.
There are still SoTs aswell.
