yeahh look, as much as i hate jump swing and jump stab abusers, there is a really easy way to counter the long spear.
all you need to do is stand still and hold your block down. if he gets close to try and kick slash just back away.
see who loses their patience first.
if he tries to run just follow him.
You forgot the part where it's 2 v 1 and one of them has a pike.
Player A: Random meleeist
Player B: Pikeman
Situation 1: You successfully dodge Player A, go for Player B in the back because he can reach you from a mile away, he blocks your swing, player A catches up, swing at your back, you're dead.
Situation 2: You decide to focus on Player A before engaging Player B, Player B stabs you through his teammate from a very safe reach, you're dead.
Situation 3: You decide to play defensively, Player A swings at you, you block, Player B swings at you at the same second Player A swung at you, you get stabbed through Player A because he used his mana to become ethereal while Player B was stabbing through him with his long reach.
Situation 4: You decide to play defensively again, Player B is the first one to engage you, you block, your stuck in that needlessly long down-block animation compared to the other blocs, Player A overheads you, can't block because you're stuck in that down-block animation. Assuming you didn't die, go to Situation 3, Player A swings at you, Player B stabs your guts while you're busy blocking Player A.
Now, change all these situations with 2 or hell, even 3 meleeist that doesn't have any pikes and it's suddenly much easier because you don't have someone with a weapon almost thrice as long as most weapons effortlessly controlling the tip to stab through his now ethereal teammates by just wiggling his camera around.
