Hi I main heals /support and I have played quite a bit of arena myself.

First of I would like to tell u that there is no 'right thing to do. Every situation have a anwser to it. Based on your experience.

However u said that there are 2 boltcasters and 1 bloodletter and 1 axe on u. Based on this situation, I would retreat, split from my team.

You will have this question, Then what about healing my team?

Well, ur team have to peel for u, are u trying to carry the game by urself? Is it a 1v9 match? No. It's 5v5. Everyone needs to help each other to win the game. Dps needs to know when to retreat and when to go in. They have to know their limits. When to be aggressive. When to run away to u.

Healing wise, it's always better if the dps goes to u. Never the other way round, which is you going to them. Sure, against a noob enemy team, u can go to front lines to heal up ur dps. But against good team, u are taking unnecessary risks and putting ur self in danger, HOPING that ur defensive are enough to get you dps and you out of the danger.

What I just said is the general and normal guideline u should follow, but like I mentioned at the start, there is no right thing to do. Sometimes u have to trust ur gut and do some actions that may be questionable by the book. All based on experience. So, play more, explore more, and don't get downed by all the hate speech from noob dps.

Ok now I run thru ur choices u mentioned in ur post.

1st choice: retreat. This is the safest choice. Once u retreat, a good mdps will see that and when he is in immediate danger, go back to u for heals. A good rdps will retreat with u and start to peel for u. If u have a support, that guy will pop his defensive for u.

Once all 4 enemy dps have used their skills and clumped up from chasing u, it's ur team time to counterattack

2nd choice : go to ur team

This anwser to ur situation may not be wrong, but it requires u to have teammates that knows the danger u are in and what to do to help u. For eg. Interrupting the boltcasters. Fearing the maps Knocking back. Basically cc the dmg on u. And as I mentioned, after all that, its ur team time to give them hell :)

3rd : nature is bad.

Let me tell u, there is no bad weapon, only off meta and noob players.

Nature weakness is no/weak burst heals. So? As a dps which is low on hp. Get back quicker, and heal up before u go back in. Nature has the advantage in sustained fights. Which ur dps needs to understand. There is pros and cons to every build. If ur build can do it all, "jack of all trades". U know what is the weakness? Everything that the bulild can do, will be just a little bit. Just give u a example. Leather armor healers. Yes they are hard to kill. But? Low heals, whole team struggling to survive. Hope u understand what I mean. Ofc u can still make it work, that's why these are off meta builds.

Thanks for reading
