To level, or not to level

I'm currently level 152, I have been considering moving on to either 250 or 300, so my question is, is it worth it? I'll lose 81-160 WB which I usually miss out on anyways, but the current dungeon's I have don't boost me quickly enough. Do the late game dungeon's justify quickly leveling up with their monster rewards?

From what I can see from your damage, you can level to 249 and get A or S rank on 200,250 and maybe 300 dungeons. These dungeons last between 20 seconds and a minute now, so do the math based on your team.

I currently S-rank 200 with a 5 hit and 250 with a 10 hit, I'm just not sure how much more difficult it is to get 3% on the higher dungeon's. My team consists of fire, air, water and dark infinite, none are "+" so I guess if anyone knew the damage requirement for the 300+ dungeon's that'd help alot.

300s are basically the same as 250s, with a very slight HP bump. our dungeon teams are pretty much the same, and I usually use 10-15 stamina on 300s. 320s are about .5%-.7% per 5x, not sure about anything higher. just hit lvl 241 so I havent seen any 340s yet

dungeon team down here --vvvvv   but I now have Earth Outer and Holy UGod

*edit*
saw 2 lvl 340 dungeons, I used 25 stam on both of them for S rank. full Infinite set might cut it down to 20 stam for S rank

i would lvl up. farming gods and sgods is way better than mass combining ultimates..
