on the contrary fighting people you think are twinks should get you more prepared for fighting the real big boys
the real big boys will be another few steps up from anything you will fight in lowbie levels... Zerg/Mont/LOB/Exodus and all the rest of the naughty 6 man players who organize themselves to be better and more optimal
they are players too just playing the game and trying to enjoy it, i don't think they would take much enjoyment from lack of challenge... but its part of the game you beat whats infront of you... they can bleed just like you do no one is immortal not even twinks or organised wb/6 mans...
its like if i went full autistic and brought leading organised warbands 24/7 to tier 1... i am within my rights as a player to seek the same enjoyment as others its been many years... just if i put in extra effort with leading, setups, gear etc... its very overkill and a bit harsh but also part of game. I haven't done so yet, but the possibility remains and event encourages it. If i did, I am not a troll for doing so, just another player playing the game. But one who is less salty.
