Suggestion: Raising taxes: only in turn 2+ after conquering

[tinkthank]

For the following reasons, I would like to see the ability to jack taxes to 200% in a newly conquered province be possible only when you own the province for 2 turns (or, alternatively: if you have a supply line to a friendly fort, but this would require huge amounts of code change I bet).

The reasons a wise man pointed out to me: Sneaky troops taking over a province behind enemy lines can pillage to their hearts content, but they could also move on -- but the province's unrest will skyrocket due to taxation, so that the original owner is doubly penalized when he takes the province back.
This seems unbalanced simply because there is no counter to it and no reason *not* to do it: you get returns for zero risk, wheras pillaging requires that you spend a turn with your units reaping that money and causing unrest. Taxation gets you the short-term money and the annoying unrest for the original owner without any additional effort on your part.
One could imagine that inital conquerers need at least 1 month to install and take over the burocracy in a province which would allow them to double taxes.
Thus I suggest: Taxation raising in provinces newly conquered from enemy players is possible only after you own it for one full turn.
