Max hint window is only part of the equation. If it is down longer than Max hint window, a repair will still fix up the node for you.
The max time a node can be down before it must be re built is determined by the lowest gc grace setting on your various tables. By default gc grace is 10 days, but it is configurable on a per table basis. If a node is down longer than gc grace you risk reviving deleted data. This of course depends on your tables and data mutation practices, but it is a good rule to follow in general.
