Hiya got a few stuff in the game that I have seen others have but not sure how to go about getting it can u help me please?

1) Was replaying some CW and notice some of those player's heros have angle, half angle and angleII. How do I go about getting those titles for my heros?

2) After lvl 50 lab open up lvl2 easy. Tried it once at 55 and got killed after the 3rd square those mobs are tough. May I know at what lvl and power were you when you started on lab lvl2 easy?

3) How does 1 upgrade his/her guild? Reach a certain amount? Have a certain number of members or what?

Thanks for the help
