How to adjust to 1/2 NLHE with a $5 to come in rule

[myxomatosized]

At my local casino there's this weird rule in the no limit game where it's $5 to see the flop, but 1 and 2 blinds. how might one adjust to this format? the minimum raise is to $10 so basically i never "raise" when i'm first into the pot. i always "call" 5. but if someone has called 5 infront of me, i treat it as a third blind and raise to 15 or 18 or whatever. only it's not really a third blind, cuz that person willfully put in $5 after looking at his cards.

so anyway, should one play tighter than normal in a game like this, since the blinds are such a small percentage of the future betting rounds?
