Power armor is given to you too soon and is too OP in normal gameplay and worthless in Survival without mods because it gets shot off too easily, makes you a bigger target and the fusion cores for it weigh you down worse than an overweight geriatric grandmother.
The principle idea of changing power armor into a more vehicle-like thing instead of a wearable and limiting its usage through fusion cores are both solid ideas but need some serious additional work and polish. Power armor as it is now is presented to you as a solution to fighting hard fights but unfortunately in standard Fallout 4 all enemies except some bosses are balanced around you not being in power armor.
I like that they changed power armour into something more than just "here's the best armour in the game, wear it always and never take it off" but the way they did it is clumsy and indicative of the fact that Bethesda doesn't really know how to make open world RPGs and would much rather do something like Mass Effect, a much more linear (albeit branching) type thing.
Also seriously fuck how common Power armor is. Fucking raiders now have power armour. Raiders. Chrissake. And don't give me no lip about how it's a frame now and it makes sense that people would weld stuff onto it, why the shit are the frames so bloody common then. Power armor is supposed to be a rare thing and facing off against someone in power armour should be a terrifying prospect. Not a common sight when clearing raider nests.
If you're playing Survival mode you don't need a mod to craft dirty water. Any empty bottle, such as milk bottles or beer bottles, will let you collect dirty water from a water source, or purified water from a water pump in one of your settlements.
But I need glass for building. I don't want to spend potentially valuable glass on getting water. Also it peeves me that drinking RADIOACTIVE WATER and eating RADIOACTIVE FOOD is somehow fine-but-a-bit-annoying.
