Idea for "League of Legend 2"

As a fellow summoner, I have played league for over a year now. It is almost part of me now. Sometimes I wonder to myself why do I play this game, I no longer feel as much excitement of playing this game as when I first started playing league. Don't get me wrong League is a great game, it's just that I think, I don't find it as entertaining anymore. So when recently the leak of Riot games creating a new game I thought of something brilliant. League of Legend came from a custom map of Warcraft 3, Dota. I didn't play Dotam but a custom Warcraft 3 map I LOVE playing was called Island Defense Roc. I am here suggesting almost begging Riot to maybe make a game based on it. It's a ridiculous idea, I know. A random student asking a huge company like Riot to create a game just because he enjoyed it, but I thought I might give it a try. If the idea seems bad feel free to stop reading at anytime I understand, I just wanted to give my personal suggestion in hope to help RIot. :)

So the point of the game, "Island Defense Roc" is fairly simple, think of is like a game of tag. The titan is the user that's "It", while the defender are the one that's not it. The objective of the game for the titan is to make all the defender it, while the objective of the defender is to kill the titan. A similar Warcraft map of this would be "Vampirism" which is quite popular. As titan you get like 9 titan to choose from, while as defender there's 2 types of defender, builders and harasser. Builders are the one that obtain as much resource as possible which later can be build to make bases to defend against titans, while the job of a harasser is to harass the titans. There's 2 type of resource for builders, wood and gold. Wood you can obtain by cutting it by your builder (Main character) or harvester. Gold however is a bit harder to get. The only way for builder to obtain it only by attack the "home" of titan as I like to call it, which is fairly hard, since you can only attack it with your character and he gets killed by the titan you become it. Wood let's you build many of the basic buildings, while gold let you build advance buildings and train advance troops. On the opposite the titan only have gold as resource, and you get that by destroy building and unit of the Defenders. Titans also have levels which levels up by attacking other buildings. That's essentially the whole point of the game, I probably missed a bunch of important points, or I didn't explain it clearly, so here's a video: http://www.youtube.com/watch?v=C0esPil8DzM

As you can see(hopefully) it's a very interesting game. I thought it can work very well with league of legend. So when you start there will be 2 exp bars one of you as defender and one as your titan. (This is due to the reason like support, titan is a position no one wants to be in.) Only when you reach level 30 on BOTH defender and titan then you can start playing ranked. as you might've guessed, there would be 2 ranking for each position. You can only go through promotion match( silver to gold) only when both the position is in 100 points. I thought that the game would work really well with the league system.

This is just my thoughts and suggestion, thank you so much to take your time to read this. I understand making a new game can be really difficult, and most likely my idea doesn't even make sense, but I can really see this game as big as League of Legend. I really do. Thank you for listening :) Enjoy your day.

P.S. I have bad grammar I know.. Not the best ENglish student as you can probably tell :(
