New Player Guide Feedback- about the roles guide

Currently the introduction to champion roles just gives a short paragraph about what the role is for and then links to all the champions listed in that role.

My issue with it is that's a little misleading as that stuff is kinda outdated and secondary roles are still included, IE Fiora shows up as an assassin, Blitzcrank doesn't show up as a support etc.

Also as cool as dragon trainer tristana is, she doesn't convey the idea of a marksman very well, she doesn't have an obvious bow or gun showing.

Lastly, this is just a suggestion but it might be helpful to have a short video that shows a champ from each role in action briefly- not unlike the video used to advertise SKT skins, just like, Sion charging in and hitting people with E Q for tanks, Lux blowing someone up for mages, etc.
