Why do endgamers have to buy War coins and beginners get it for free

[Sytro]

Here, some info from the post that introduced Warcoins, bolded out the reason.

@Saltypatra

Warbands are a pre-designed team that players can use straight away in battles (similar to a Starter Deck in TCGs). Warbands are primarily aimed at newer players or players who wish to start dabbling with team building but want an existing team to build off. They also contain extra banners and team slots, so there is something there for experienced players too!
