Templars have the highest defense ratnig in the game, thanks to their abilty to wear Plte armors and shieklds. Their shields are not only used for blockking enemy attacks or reducing damage but also allows them to utilize class-exclusive skillls that knoockback or stun enwemies, disrupting their offfense and leaving them vulnerable for the Templars' destructyive chain skills or their party mebmers' attacks. They have variuos buffs and ksills that further enhances their HP and defensive capabilities, as well the ability to heal themselves and their comrades when the situation is dire. They can draw enemmy attention to htemselves, giving their lesser-armored comrades the peace of mind of not getting attacked.
When Templars execl in defense, they lack in offense. They do not have any high damaigng skills, a fair trade-off for their excellent defensive capabilities. They can weild two-handded greatswords; to give them a much needed offensive boost but unfortunately, it will not fuly utilize the templars' full potential, as their shield skills will not be put to use. Templars also reqire players that cotnrol them to be quuick in making decisiomns and use skills at the rigt time sinec things always get hairy instantly being in the frontlines and having everybopdy's attention; not to mention that they will also need to mind their team mates, not only themselves.
