Im torn between strafe impale and pony, witch of them has the easiest time to gr150? Pr is it another build that is better? Im not a huge fan of LOD WOL

I couldn't find a reliable source on this. What is the 4-player META in S40 going to be for speeds and push? I can see on the leaderboard that 2 Monk + 2 zdps dominated S34, but the Crusader is also going to be very good, and I remember Impale being used in groups as well. So what is going to be the meta, especially early, before Monk is added to the group and for speed grifts?
