Losing team gets PUNISHED for losing ; Defense weak in general

Inner turrets and inhibitor turrets are now lasers, meaning, in my opinion, they sacrifice wave clearing in order to slow enemies. Despite the various choices of mobility items/enchantments and mobility abilities

Here's a quote from Riot.

I'm sure we've all had the unfortunate task of trying to single-handedly stop a split-pushing Jax (or Tryndamere, or Zed, or... you get the point), only to get murdered under an inhibitor tower we thought was safe. These changes are focused on creating "generalized defenses" against split-pushing

What the hell is dragon buff, baron buff and Elixir of Ruin as well as turrets nerf doing then?

Dragon's Wrath (4 stacks): +15% damage to turrets and buildings Aspect of the Dragon (5 stacks, repeatable): Doubles all other bonuses and your attacks burn enemies for 150 true damage over 5 seconds. Lasts 180 seconds.

    All Minions:
        Now match 90% of average movement speed of nearby champions, up to a limit of 500 movement speed
        Are resistant to slow effects
        Non-super minions have 75% damage reduction versus area of effect, damage over time, and persistent effects
    Melee Minions:
        Gain +50% movement speed when within 800 units of enemy minions or turrets
        Size is increased
        +75 attack range
        75% damage reduction versus champions and minions
        30% damage reduction versus turrets (similar to cannon minions)
    Ranged Minions:
        +20 attack damage
        +50% missile speed
        +100 attack range
    Cannon Minions:
        +600 Attack Range
        +50 Attack Damage, but Attack Speed is halved
        Attacks are now Area of Effect (200 range) and deal 2x damage to Turrets.
    Super Minions:
        +25% Attack Speed.
        Gain +50% Movement Speed when within 800 units of enemy minion or Turret.

+15% bonus damage to turrets, and the Siege Commander buff for 3 minutes SIEGE COMMANDER Nearby minions gain +15% bonus damage to turrets and gain movement speed based on your movement speed.

In all respect to Riot's effort. What the hell is this? Cannons literally outrange any turrets with a baron buff!

Another problem is minions-only backdoor. Have you guys noticed how often minions will destroy your turrets? Minions are extremely powerful vs towers. You need a defender and this is how it's punishing to the losing time of the team.

Those changes are pretty tough if used correctly but counterable by a good, defending team. If you're losing and a Master Yi starts backdooring your top and bot lanes, could you actually do anything beside for losinng manpower to stop him and STILL lose turrets either way? All those changes simply makes sieging easier, forcing defenders to focus on one lane (Lose two lanes) or spread out over two or three lane, dying and losing champions and even prehaps risking a Ace and a instant loss.

This is my opinion and you're welcome to challenge my claim but without saying "Stfu" without a explanation.
