If someone has only 80 attack and you fight them with 99 range, you're going to have a clear advantage as you're going to be more accurate. I can tell you from experience bro, I have taken out lvl 120s-130s with my 99 range and 93 def in fight cave and in duel arena..
that depends on gear. i guarantee you that a dude with tank gear(whether it's welfare or not) and turmoil or leech atk/str using a dds is going to 35-35 you faster than you can 76 him, as tank gear has an obvious advantage against ranged gear. ofc you'd be using ranged 'tank' gear so you might have a nice dfs(if you're not welfaring) but that will make a mininum difference tbh.
also dude, i'm talking about wildy pking. people play so much differently as they're actually risking their gear as opposed to fight caves where you'll get some wanker going mental with his full torva or some shit. also duel arena is also completely different(even staking) as the tactics one uses are entirely dependant upon the rules set.
regardless, by the time a 'ranged tank' is maxed, they're not good enough to stand up to fc hybriders unless the bridder really sucks.
