Turrets and Epic Monsters not strong enough

Okay, I've been playing a lot pre-season and some of the turret stuff has been an issue in my eyes since last season.

1. Turrets just aren't strong enough: Late last season and pre-season turrets, especially the outermost ones can be taken down so fast, its ridiculous. One big minion wave is all you need and a jinx, jax or even a garen can finish it in seconds. It's crazy. I've never seen turrets being taken down so fast. a. They really need more armor. b. they need faster damage scaling. Turret diving is way too easy solo amidst the outer and even the shielding turrets. Turrets no longer have that 'feeling' of safety. c. Nexus turrets need WAY more power. Even with super minions in one lane, one nexus turret always goes down so fast regardless of the new beam mechanic. Nexus turrets needs way more power. They're actually a joke.
2. Dragon is way too easy to kill for the rewards it gives a team: Dragon is honestly a joke to kill. It's one attack can be dodged so easily that it can be taken down at level 4 by three people. (jungler + bot lane.. .tried and tested). Mid-game the dragon is SO easy to kill, it feels like piñata. The fight doesn't feel epic at all. Feels more like a stroll by, power harvest more than anything.
3. Baron is doesn't feel strong either: Baron's abilities are also so easy to dodge its crazy. Again as with both epics, they really only focus down one champion so as long as you have 2 or more.... both epic monsters are so easy to kill...

This needs to be fixed.
