Viking beeds these buffs so badly

Vikings need a buff for their lategame. I propose the following options:

• Dragon boats tgat shoot multiple arrows like chukonu LOL so OP

• free ecobonus like free wheelbarrow or the like to really boost this civ!

• make their unique unit more viable by giving them more stats. Maybe introduce some unique techs that would automatically heal your units or give bonus against strong mellee units like knights. Historical justified because berserkers were awesome and kept fighting (healing) and were able to take out better equiped units (like cavalry)

• make the civ more unique by focussing other bonuses on dominating on water in early game. Give them a faster access to galleys by making docks cheaper. Might need testing so its not to OP for grushes. Maybe to nerf a bit disable firegalleys for them...
