just bought this game today
Question 1: Guardian has a lot of self healing capability to make up for the lower HP pool. If you want to concentrate on healing others, then you may need to change the way you think because this game does not want a traditional holy trinity of tank dps and healer.
I hear elementalists heal others better than guardians, but again don’t focus on being a “healer”.
Question 2: PvP is fairly simple with guardian in that the meta right now is to be “bunker”. Meaning you survive a lot of attacks and self heal a lot. While doing this you prevent the enemy from taking the point you are standing on. If you go full bunker you will not kill too many people.
If you go full offensive, there are some options such as Judge’s Intervention (teleport) and Whirling Wrath on the greatsword or other bursty type abilities. There are offensive options and a lot of people have shown them in various videos on this forum.
The majority like to emphasize the built in mechanics of this class and focus on defense/support though.
I have played LoL, but only for a week, I assume Jarvan is a defensive dps type character that diverts and redirects a lot of damage. You can do that with guardians via burn on blocks or the retaliation skill, but it is difficult to do right as you can only block 1-3 attacks before you are just sitting and waiting for cooldowns to refresh.
Guardian is bad. Roll a thief they have mad “skilz”
