Welcome to snowy

Level scaling works so badly that some ppl really do want l100 ppl for pelargir which needs high dps for the bosses

But for sure I do know that lot of ppl believe that low level (rank 6 / max promo pts) could not manage any other bb's either where dps is not as much needed
When that is the case, I atleast do know that they might not really know what they are doing and im actually better of grouping with someone else
to actually get full plat runs and so

Your best bet is then to try to form the groups of your own and maybe also then say that if one is afraid of lower lvl, dont join :P
