Question to medi Guards
1. gs scepter/focus does really good dmg. it overall a viable build. But there are better dmg builds (mesmer and thief). Thats why it will atleast not be meta. still a good build
2. Knight makes no sense on guards. Guard have a really low hp pool. without any +via you end up with 11k hp. thats just not enough. So you either need vita in the amulet (marauder on dps guard) or atleast in the rune (rune of soldiers on bunker/clerics guard). The only way you can go without vita would be to pick the GM in Honor (giving extra vita) in my opinion
Burn Guard is pretty effective in standard level play, but it’s a bit of a gimmick that’s likely to be nerfed eventually. Power Medi Guard lost quite a bit of damage, and isn’t really as effective anymore, sadly.
Marauder with rune of strength/pack/X and sigil of fire+air, with GS + Scepter/Focus, will make you a very good dps class. Alomst all guarians actually play a dps build with gs and x/focus.
You can use a Zeal/Valor/Virtues build with full meditation utility. Heal and elite can be different if you prefer to have more defence or more damage.
Knight in spvp isn’t the best. it can be very good against direct damage classes, but there’s a large amount of condition builds and if you have only 11k of hp you die quickly. If you don’t want to play in marauder you can chose the amulet that give vit+pow+prec to be more defensive but also deal damage.
Anyway, guardian is one of the best classes of the moment, it will still be in the meta.
Fight against a mesmer or a necro can be hard, but you can fight and defeat a large amount of classes without so much problems.
If you want something different you can also try a Condi Medi build. radiance, Valor, Virtue, full traits to apply burn and full meditation, shelter and renewed focus (you can chose to use Purging Flames instead of Smite Condition to apply burn and clean conditions aoe). It’s not the best build of the moment, but it’s funny.
