You owe me 20k for this tutorial. ;)
1. as shielder you are not soppust to be offensive player
2. longer the weapon,the faster it is. if you see glaive for example it have 90 speed,but it have very big reach so if player go backwards he will always outspam you,and he will always be faster then you.
3. moust of 2h have 18/21 or 21/18 builds,so they have 6-7 or more athletics,so they move faster then you. You have shield that slows you down a lot.
4. shield speed plays big part in fighting,and weight of your gear. So you need to get any of knightly shields that have 100 or over speed,and use some lighter armors.
5. always be close to team,alone you are easy pray. You are support class,not some 2h hero/rambo.
6. pick longer weapons,or pick some of the picks (steel,military),but i would say knightly arming sword and nordic champ is only swords you need to use because they have pretty big reach.
7.avoid big clusterfucks because you have small reach and everyone will tw you a lot.
8. moust of 2h are spamming sluts so if you see that he is faster,turtle and move back to teammates.
9. moust of 2h will use kick,so don't go straight at them,be little in side to avoid that.
10. know where to move,and when to attack. don't follow ppl in fight with mob if you don't know who they are,becasue moust of ppl run away and let you die.
11. don't attack alone ppl with big polearms or with axes,or you are dead because they will smash ur shield and backpedal or spam you to death.
