I think it's just a difference of opinion but I feel that the way the key wardens are placed and with their huge aggro radius is fine as of now.
I feel like any more indicators and they might as well have a set location for them, which i think undermines the whole randomized dungeon map idea.
That's fine for coop you have 4 people looking in all areas solo take alot of time. I've missed him because he was one screen over.
Solo play should not be penalized maybe make it just an option for solo play. 4 people looking all over the place take no time at all to find any of the wardens.
What I am trying to say is for solo play we should get a marker or ping on the map once we are close. Then I could farm keys a lot more efficiently. Instead of taking 15 mins just to find the warden.
Because I chose to solo key farm because it gives me more of a chance for a key drop(4 for 6 BTW) I would rather do 9 runs solo to get two full sets of keys than 15 to 20 coop.
I even have friends that all they do is MP 5 coop key farms I end up with sets faster because I solo.
Act 1 key warden always agros anything remotely close to him trees, packs, whatever.
Act 2 key warden is usually sitting by at least one pack, and the pack has ridiculous affixes like arcane, desecration, molten, and frozen.(so agro the pack out if you can)
Act 3 key warden just started recently hiding up stairs you normally don't co up.(missed him three times)
I have a broad range of friends on D3 I have some extremly strong players that can do up to MP8 and other that won't go above mp 3. It pretty much comes down to DPS people that were farming act 3 before the patch with issues can't do over mp 3.
MP 3 difficulty = Patch 1.04 that what was told to all of use the played on the PTR.
This all goes back to the discussion whether or not monsters should be on the map, well when you trigger and event say in the woods act 1 they do show on the map. I know part of the game is the anticipation of what's around the next corner. Well that's should be your option. In other words put it as an option\gameplay\show monsters on map.
Everyone knows if you get a pain pack and you go where you have not been you are going to agro something into the mix. In coop games everyone is like who was the idiot that went the wrong way. Show monsters on the map wouldn't have that problem as much.
