Either more energy or faster energy regeneration et al.
I have three characters, who of which are level 35. Yet, when I finish gardening with a few plants, so one pet training,, I have little energy left for fishing... In fact. when plants get pests, the energy cost can be very high alone!!
I strongly suggest that you either provide a bigger energy pool upon leveling or faster energy regeneration. Frankly, one point of regen every 15 minutes is absurd.
Also, chat system is HORRIBLE. We can't even communicate simple things do to your filter. I wanted to say incomming healing and I couldn't do that. Please consider improving the chat system.
