Hey!
Allods isn´t dead but there are not as many players anymore as there were years ago.
It´s playable and especially if you have some friends already to play with I´d give it a try.
I had an Allods break too and now I`m playing for a while already again with the right people maybe you´ll enjoy it again.
A few Guilds I think around 4/5 are doing Nihaz weekly (Which is the latest Raid); BG usually pops quite often during the day; There are many Dominion partys so yeah it depends on what you´re looking for tbh. It´s like everyone knows everyone which can be kinda annoying but also nice
P2P also seems going quite good atm. I´m on F2P but from what I`ve seen and from what I´ve heard they´re doing Nihaz too (Not sure if they finish the whole raid or not tho) but if you´re interested in playing on P2P I can tell you some ingame names to contact for guild; help etc.
I hope that was a bit helpful at least as I´ve said maybe you and your friends will enjoy playing it again - Always nice to have some people coming back to the game and if you have some more specific questions feel free to ask here as well as in the Allods Discord!
Have a nice day!
