Turtles will sit and wait for parries or guaranteed safe attacks. They may back pedal so youre constantly out of range and have to attack into their range. Turtles will wait to parry a light attack and then gb into a max punish. They wont expose themselves by attacking. They will spam emotes and "good fight!" After the match is over as well.
Its when Warden play vs you and move that shoulders up down all the time and dont even think to attack you, i mean you can provoke him, show him your ***, tease, insult and whatever, still he will continue to move that pair of shoulders up down and wait... And when you finally attack he will block/parry and go with that ****in zone attack.
Turtles are usually defined by their reliance on blocking an opponent until an opportunity presents itself to either parry an attack or GB their opponent for an attack. After attacking, they would rinse and repeat the strategy. This method of fighting can work well for most heroes, but some heroes excel at this strategy better than others.
