Always room for a question ... but the basic idea i undestand it. Anyway ... does not appear anywhere, yet ... although it has specified that will deploy..where? ..I don't know.
But i believe, as described in topicul above, that refers to the total Gb boost and probably will be added and the watch tower/monastery because if it were calculated separately I don't know how it will be split on territories.
support pooling = Gb attack + Gb defence + watctower/monastery + bonus from guild level ...
It is only an assumption.
