If you are several low-geared players wanting to go to instances together, why don't you just make the group yourself? This also goes if you're a solo player and you for whatever reason aren't getting invited to other people's groups.
Playing a MMO does not mean you're entitled to people's time and help. You are not entitled to an invite just because you apply to a group. Applying to someone else's group also more or less means you submit yourself to whatever sort of group they want to make and their roll right rules, gear expectations etc. If you want to be in a group w/o gear check and you cannot find one, make it yourself.
On elyos side there are a few legions focusing on doing things together and helping eachother gear up, most likely it's the same on asmo side. That ofc means you are also expected to help others. Perhaps look one of those legions up if you are interested in spending your time in this manner?
