Updated SR - Strategic Changes

Riot talked a lot in patch notes and dev blogs a lot about strategy.. I'm wondering if anyone at riot or anyone in general ever thought about base upgrades... It could be a nice way to prolong games for those late game demolition machines to actually make it to late game.. for example.. anyone on team can buy in store something that would make the inhibitors respawn 1 time in half the duration or knock all enemies back as it explodes, or tier 2 turret upgrade, that makes the shield health double, or do more dmg. inhibitor turret upgrade that makes its laser hit for half dmg, but hit surrounding units, maybe a nexus buff that causes it to spawn 1 extra minion, that's worth no xp or no gold per wave. Just seems that the base is the base, if the enemy gets into it, your pretty screwed at this point.. they either have minions or they don't... but if that turret could take out the minion wave in half the time, they have less time to push, and your team has more time to react... spend a little on your base, increase your odds of winning by a little.

thoughts?
