Firebrand support better vs spike without buffing heals

I was thinking about it for a little bit and the thought hit me.

Unbroken lines, keep the 300 toughness and add to it something similar to :https://wiki.guildwars.com/wiki/Spirit_Bond

Could be ran off if takes % of health or something else.

Protective Spirit would also workhttps://wiki.guildwars.com/wiki/Protective_Spirit

One or the other

Firebrand is way too weak vs high spike dmg like a scepter elementalist, buffing heals would alter interaction with less spikey damage builds.
