Guild Wars 2

Weather
These are some of ideas for weather effects(which can be dumbed down for those who already have low fps) in some zones. They would appear in large sizes at designated spots around the zone. They add debuffs like the statues of orr [lyssa you cant heal, grenth you are poisoned, etc] and some buffs while in the storm or weather and apply to all.(npcs, enemies, allies/players, pets) Last a short 10 minutes or less and don’t appear often.

Shiverpeaks: Blizzards that limit visability and slow movement(slightly, like 3% or 5%) Ice based attacks and conditions(frost) are enhanced by X% in these storms.

Crystal Desert(When its added): Sand storms, similar to blizzards but don’t slow movement. Instead they put a slight chance to miss when attacking(3% or less so it isn’t impossible to cope) and buff earth based attacks and bleed.

Ring of fire and close to Mount Maelstrom volcanoe: Heat waves that blurrs vision slightly and buffs fire based attacks and burn.

Water based zones(bloodtide coast, Sparkfly fen mainly during morning): light fog with slightly harder visability and buffs water based attacks and healing amount slightly.

Fields(Brisband Wildlands, Gendarran fields, harathi Hinterlands, maybe queensdale): Heavy breeze that slightly buffs movement speed, stealth duration, and air(or lightning) based attacks.

Orr: Acid rain that buffs poison, fear duration, and vulnerability duration slightly. Makes the sky around you darker; and dims brightness.

I know there are weather effects but they currently are only for looks. I think it is a start but would be nice to build off of them. ^^

Aggro
This could apply to dungeons as well as outdoor pve. A new system that makes you pick your fights or avoid them altogether by slipping by(such as you DON’T want to aggro that group so know how to avoid them) Some new aggro types could include:

Screamer: Kill target quickly or they will “call for help” and link all enemies of that family within a large radius.

Utility/elite/profession skill aggro: Remain passive or have very short aggro range but have a large aggro for anyone who uses a utlity, profession, or elite skill. (If you have a banner or elementalist weapon equipped, they do not count as utilty but casting a banner or elementalist weapon does.) These enemies would be more for dungeons and come in groups.

Sound aggro: There is a walk option in the game which would be of use for this aggro. Could be a not so dangerous enemy (slime or a ghost) that your better off fighting or a sound activated trap(running, using skills, jumping) that you want to slip by or suffer. Many uses for this from going by a trap or avoiding a sound aggro legendary/champion.

Not a fan of the aggro part but weather sounds fun. In fact, I would even rewrite those numbers you have. 3% or less wouldn’t feel like it was affecting me. 5%-6%+

Go big or go home

Well its just a base idea, values can be adjusted but It shouldn’t be to the point where its like 6% miss, that would get annoying.
