Dragon and Towers need a buff

When I say Dragon needs a buff, I am not talking about the buffs that the Dragon gives you upon killing it, but the Dragon itself. It's way too easy to kill that allows for permanent buffs throughout the game and with the upcoming changes to Dragon's buffs.

Dragon's Wrath (2 stacks) changed to "Grants your attacks on turrets an additional firey burn for (10 x level) over 2 seconds." from "+15% damage to towers and buildings." Dragon's Dominance (4 stacks) changed to "You take 30% less damage from turrets" from "+15% damage to Minions and Monsters"

The idea I have in mind for Dragon is to have a greater scaling. It simply does not keep up with mid and late game and pales in comparison in strength to Baron whose buff is temporary. I think each time the Dragon is killed, it should have a scale boost upon its next spawn so that the next dragon buffs can be harder to achieve. Too many times have I seen the Dragon get solo'd with ease in mid to late game, and it should not be that way, it should be a challenge and award to get more dragon buffs than just sitting there AAing it. It should require a team effort, just like Baron, to kill it in late game.

As for Towers, the nerf to its armor needs to be reverted and the damage needs to be upgraded, especially at the inhibitor towers that are poor and even though the argument for these towers is for them to prevent minions from pushing in, this is not the case, as a minion wave that goes unnoticed can do quick work on these said towers.

This should not be happening.

There have been many suggestions for the towers such as making them do true damage, having them fire faster, some even suggesting they do multi-shots on multiple champions that try to dive you.

Those ideas have been downvoted.

So my question is, what do you guys think? Do you think Dragon and Towers need a buff, and if so, how? If not, why?
