Reaper of Souls working fine !

Well, since nobody complained, you could guess that Reaper of Soul is working fine, at least in terms of multiboxing

I saw Pokey playing too, earlier.

I didn't try to play with isboxer yet, as I only bought the addon for 1 account (I have 3)
For the moment I'm leveling my main char to level 70 (level 66 right now) then I'll do some paragon XP for my alts.

char 1 level 60 invite my 2 others char : level 60 + level 70 in a party
This way I'll probably able to play in torment 3 or higher as the ennemy will be level 60 only They'll go down easily.
My main char went from 164K DPS at level 60 to 225K at level 66, looting only a new yellow bow and a quiver.

Also I found some crazy items in ROS, like a yellow bow level 61, but required level 47, huge DPS on it really good for PL.

You can equip your level 60 dudes with level 70 reduced level yellow gear... But I certainly get more Paragon XP playing 1 hour Torment I at level 70, than I got when playing 1 hour at Paragon III level 60.

Just keep your rings and amulets tho, I don't think you can find some with reduced level.

Also with the "bounty" system, playing in RoS is very different. You don't really need to do that same area over and over again till you are bored...

But for sure 39.99€ x4 hurts, too.
