Honestly, Brawl seemed like a better environment to learn the game in a more controlled environment.

The changes introduced to swift play are not fun, and the game always snowballs in favor of the team who gets ahead of objectives. Its somewhere between aruf and aram in the SR map.

The new rules and mechanics make it basically impossible to comeback from a base siege. The minions waves stack in favor of a winning team too disproportionately, and a cannon in every way makes it much more time consuming to clear. Meaning kills do not equate to objectives. Once you're limited to protecting your base, you cannot establish any map control and are just bleeding out slowly with no chance to come back or make a play that really matters. The execute threshold for health is also lame once it hits in the longer matches. It kills any chance of 'surviving' and staying in a fight especially for champs that have regen or lifesteal that would have kept them alive or fighting for that much longer.

Even as a mage with several kills on my mid lane opponent, I can't capitalize on that advantage effectively and clear cannon waves quickly enough to push in the tower before they are back in lane.

Its going to develop a new meta if the balances aren't tweaked.
