Workaround for 50% XP Penalty on Pet Damage?

[Lokked]

Regarding the xp penalty when your pet does >50% of the damage while solo, I recall from live, you could group with 1 person (perhaps another necro soloer) and stay far enough away from each other so as to not leech xp from each other's kills, and you would still receive "Party Experience", negating the XP Penalty. Is this valid for P99?

PS. This also worked for getting the XP bonus due to being in a group, but in classic this was so small that it didn't matter, until they juiced it up in PoP, I believe (but then later nerfed it).
