Is there big diffrence for example to play with ~120ee gear instead of ~80ee gear?
I play mostly solo for now and it takes me like 3days to master quest with quite much screen time
i usually break my climbs up into 2 parts, the 1-55 and 55-mq.
on hardcore i irregularly use a 14x ee level 45 polearm all the way to level 71. i usually expect this to take ~5 hours. However i usually use only 1 piece of ML gear and i'm lucky enough to have found a 160+ ee 39 dex chain which makes level 60-71 a breeze.
on softcore i use a bit more magic luck and use ~3rd best club set i'm aware of.
For 1-35 i'll just whistle because the drops don't matter, yes a 160ee level 25 item could drop but a 200ee level 35 could drop at level 35+ and seeing my gear can slaughter everything anyway, i might as well go with higher level mobs, although 35 is generally a good time for me to start on softcore.
1-35 will be ~2 mins per level, so about 70 minutes. This is just whistling.
35-55 is slightly harder and exploring with at least 1 magic luck item. so about 5 mins per level, which is close to 2 hours.
55+ i would be using 10+ ML armor/charm and a 250ee club and be exploring again, again probably in the region of 5 mins per level. main reason it's that high is i get distracted and look at other stuff.
So about 5 hours of play time both cores to be honest, i "could" cut this down to about 3 hours if i whistled the entire way, but if i intended to do things fast, then i'd try and get 4-5 man group climbs going where these take ~50-70 mins to go level 1-85 depending on the gear of the group
