3 Marking lights is a fucking joke

So while creating this post i have 89.50% on AMX elc bis. And its 1st tank im trying to 3 MoE. I found a little problem in MoE system playing lights. I played a game 1k dmg 2k spoting and my % dropped. I realized something. MoE system doesn't count combined dmg but only DMG that you did. So im going straight up to my point. WG wants you to camp in LT to 3 MoE it (maybe not in every LT). But camping LT is just lost of one of the most important tank in game. So i think that WG should did a small "rework" of counting MoE. At least on LT cuz sniping like a TD to achieve 3 MoE is dumb because playing LT isn't about being a sniper but about spoting enemy. What do you think about a small rework of MoE to siut light tanks more so there will no longer be situations like "in 1st team LT is spotting half of enemy team while is 2nd team LT is standing next to TD so his % wont go down".

Edit: i now understand that spoted DMG is splited in 2
