Best party combo for 2.4?

Hi guys,

i`m currently building up a 4 raekor team (main 1070 para, 3 slaves around 300 atm) the xp/hour is not bad atm, basically around 20-30 Bil/h but i`m just gearing up the new guys atm. I`m just wondering if u guys have already found a very efficient team for xp crazy grinding and if yes what combo do u have atm?

Thanks in advance.

Joe
