No, it was more complex than TEAM was 'screwing up' departures.
We weren't 'blindly' using TEAM.
The CAA expressed it as :
It was suggested that TEAM may have been used too routinely by the
NATS London Terminal Control Centre sequencing arrivals before handing
over to Heathrow Tower. Following discussion between airlines, NATS
and HAL a more tactical approach to the use of TEAM* had successfully
been adopted in Phase 2.
Whoever would have thought of using "Tactically Enhanced Measures" tactically ?
