You have to play during the hours russian players play. Simple as that, they're at least 80% of the server.
Concerning lfp: once you reach 60+, you can see many random parties forming for exp in partymatching... mainly TOI. After 76 there are DOZENS of random parties farming GC....randoms also farm LoA, DV, FOG, high zaken, laba 83, RBs... pretty much everything, hundreds of random parties every day. I've made 83+ with random parties only.
There are no parties <60 lvl. Simply because this 3x is fast and you can solo 60 lvl in couple hours... with these bonus start events. No need to make a party for that. Get 76+ and you can join 10 random exp/instance/rb parties every day.
No idea where are you from - but if you learn basic russian (like cbc=sws, ro=go atd...) you can start your own parties in partymatching. For example, I wanna go farm GC with random party. Usually I have full pt ready in 5 minutes. It's really easy and you can do almost anything with random parties, so get some lvl and stop whining noone will go to 20+ catacombs with you :-P
