Lagg spikes while in delve

As the title says, with my current character Tappy_trapper, I get massive spike while in delve any time discharge goes off. This only happens in delv's. Furthermore, I have tested it not to be party dependent; however, it seams even the server laggs in parties.
GGG please fix this, it makes my character unplayable when attempting to enjoy a key feature of this update.
