Simple fixes

1. Remove a bit of damage. I should not be shredded like paper when I have over 300 armor and mr.
2. Remove a bit of pen. See above.
3. Give slightly more defensive options. This cancels out a bit of the damage in the game as well
4. Remove some damage from tanks. The more damage you can take, the less you should deal.
5. Backload more of the damage for squishies. Also, make them more squishy and more shut-downable.
6. Make the game scale better out of laning phase. It shouldn't be that the laning phase is longer and then the game is right where it was at the same time before. It should be that more time was inserted into the game. Especially if Nexus Blitz is going to be a permanent mode, SR doesn't need to be over in 20 minutes. There's an inherent and implicit time investment to playing on SR. Find a way to scale the minions a little less forcefully and let games scale up naturally too.
7. Balance the runes and shards. I know this'll happen naturally over time.

I think this should generally be the goals for this preseason. Especially with Nexus Blitz coming and seeming like a viable option for short/fast paced games, the recent push for a shorter Summoner's Rift game should be negated. I think the game needs to be made longer and slower for a return to form that's sorely been missing but also I think that most of the people here are kneejerking Hashinshin fans who don't know how to not get what they want immediately. These should be the general goals for the preseason and should be ground out over the preseason. I don't expect it now, but in 2 months time I'd love for the game to get closer to this.
