New Mode concept! :D

So I was playing game right and I got real fed and had full build and all and I had that feeling, you know, the one that's just like "man, I really here was something I could spend all this darn gold on!" Cause if you do well in a game then you get full build and have thousands of wasted gold! So I thought "what if there wasn't an item capacity limit?" What there was a mode where you could buy as many item as you wanted without having to worry about that pesky 6 item limit! Obviously it would need a lot of tweaking like extra base gp5 so that people who aren't fed can keep up or more gold for assists. But c'mon guys! I think that would be really phreaking fun!! Imagine being a 50000 (fifty-thousand) HP Mundo ! Or a 2000 AP veigar ! The possibilities are endless and this mode could make it so the virtually no pick is a bad pick. You choose random every game, decide wether to go Tank, AP, or AD. Then be set for the rest of the game! For example: full AD garen where he has close to 4000 AD but is still soooo tanky! Another thing that would be cool is a change where attack speed would have to lose its cap too, or just have it extended so that you can have like 10.00 attack speed nautilus or some crap like that! XD One scenario I also like to think of is imagining having the generally hefty tankyness of Mundo and rammus combined and mashed onto the damage output equivalent to that of jinx and Katarina combined! Omg it gives me the heebie jeebies! I seriously want this to happen I think it would be super fun and awesome. Please if anyone else shares my love of this idea help it out and post ideas below! Thanks :D
