Think about it... are we really helping the lower ranked players on their first "whatever" missions if we just dive in with our super sets and burn everything to the ground or are we keeping them from learning how to be a better player?
If we play a level with them (in our super set) and they die they will say that it is because they don't have good enough stuff, but if we play in armor that is comparable to their then they don't have that excuse. Instead of blaming armor or weapons for their lack of success they will instead look at themselves and say that they aren't good enough.... yet..
We as older, more skilled, advanced players need to inspire that spark of "not yet, but I will be" in the upcoming generation of knights.
lol, this is actually an issue in tutoring/teaching as well. If you help too much, they don't learn to fend for themselves and instead become reliant on you. I was a TA and I caught myself babying my students too much when I first started, but it really is better (and sometimes a little fun) to see them struggle, and even better when you see the "I GET IT NOW!" moment :)
:P if you want to help them out, pick up a gun to do some chip damage without screwing up their knockback (so they can learn to move/aim), or a bomb, because bombs are great team weapons.
