The Shield is the weakest with its shield capabilities having to charge up first on pickup, needs buffs to lunge range then or the charge time for blocking reduced. The Scythe is the most annoying to deal with but there are enough Weapons and other Relics to counter it. Synaptic Spear is the strongest and needs already either a throwing distance or throwing speed nerf to prevent it from running rampant the entire match.
Heavy ammo is just unnecessary distraction in the mode and should just be removed in general from it. Weapons are ok in the sandbox.
That aside, the Relics uptime within the mode (as of the state 29th August 2023) is a bit too high. The Relics should be in my opinion more of an "extension" of the combat in the mode. Not "the main attraction". We really DON'T need another Mayhem-like gamemode that throws all balance out of the window.
Relics should be exclusively earned via kills and assists, no initial spawns on Match begin. People should have to work for that power, not get it gifted by being faster at a relic point at the beginning of the match.
That's all I have to say about this mode. A nice idea but still with wasted potential.
