Thanks for the kind words, I hope that this kit will help you bring your project to life 
Regarding the road map - it’s not as easy to do as it sounds. One example: I wouldn’t mind adding some character abilities to the kit, but Epic has started on GameplayAbilities module last year (for their Fortnite game) and now it looks like we might see that module in 4.9 or maybe even 4.8. So now, my implementation of abilities heavily depends on when they will finish theirs and how useful theirs is to an MMO.
Among the things that might be added soon are loading screen, quests and health regen. After that - haven’t decided yet.
Hi, please add me on Skype () since it is generally much faster than writing emails. Also, make sure you’ve done the steps in “Launching for the first time” located here. If you have access to another php hosting with php 5.5+, you could also try it - switching hosting has worked for some of the MMO kit users who had problems. (free x10 hosting has been reported to work well but I haven’t tried it myself).
From my experience, environment and props usually port very well to the new releases. As for the blueprints, when I was porting the whole kit to 4.7 it wasn’t easy because they changed something in the macro libraries.
