considering that blizzard is making LFR groups need before greed, this can't be remedied so easy. you also cannot make a ticket if someone legitimately wins a need roll.
LFR is a doubled-sided sword. the content is accessible for people who cannot dedicate their time to a raid guild, at the cost of potentially losing your dps upgrade to a tank or healer. which in part is probably why they gave it a lower item lvl.
