PC1 should only apply to high capacity and hostile pads, and it is not a profile.
i do not know Greek rules, or what the exact operation was, so not sure if PC2 might be required.
Regardless, Cat A profiles would have had him protected from OEI but not from the wires because he did not see them.
It is take off direction into an unseen obstacle that precipitated the accident, i.e. operating in PC1 or 2 would have most likely prevented this because of the obstacle survey requirements, not because of the CatA capability or profiles of the aircraft, not even if it was a single or multi engine helicopter or one or two pilots or a military pilot not a civvy pilot or an offshore pilot not a HEMS pilot or a SAR pilot and not because of the myriad of other endless irrelevant arguments pervading the prune these days. No, vortex ring, LTE and centrifugal force are also not guilty.
the sooner we fit (indeed MANDATE) helicopters with synthetic vision and a proper graphical obstacle database, the better.
