Better counter-portal?
Send two far immediately and crush in a 2v1 and let a sustain profession go mid to keep it mute as long as possible without dying. A lot of coordination would be needed in a short amount of time though.
necro at home: place all wells on the portal while capping
DH at home: place all traps on the portal

thats why you should always enter portal with blurred frenzy…

Assuming opponent is 1,3,1 (opponent home, mid, far) where Mesmer pushes their far for portal drop, allies go 1,3,1 or 1,4,0 (ally home, mid, far). Mesmer is attempting to create a no-win scenario for home player while outnumbering or matching numbers at mid, likely pushing for a Moa kill and momentum gain. If the Mesmer pushes their home they are denying themselves use of the portal in the short term.
If you cap and then push mid you give the Mesmer the opportunity to quickly decap and return to mid or full cap, in either case your team loses the cap UNLESS you or an ally can return fast enough to deny decap. Additionally, you give them longer mid support time while you cap.
If you give up point to follow Mesmer to mid, pressuring along the way, you may be able to force cooldowns and/or portal, denying them the advantage.
If you follow to mid you’ve matched their numbers or have outnumbered them. If Mesmer now portals to your home they are giving mid advantage to your team, or you can push back home quickly and deny the full cap.
If they are coordinated, the enemy team can port or split and play sides. However, this gives your team mid and acts as a reset, allowing your team to choose the more favorable fights against the split opposing team.
It is certainly a mind game, and I think the general rule of thumb (but not necessarily perfect in all scenarios considering compositions, splits, and matchups) is to refuse to play and deny the advantage by focusing the other two points (hopefully quickly and decisively) and/or pressuring/harassing/focusing the Mesmer to force cooldowns/portal.
In team fights my understanding is that Mesmer’s primary goal is generally, but not always, to provide Moa kills to push momentum. If you can effectively deny that by harassing/forcing cooldowns on the Mesmer, and/or supporting the Moa and denying the kill, you’ve largely denyed the Mesmer their utility (map presence and Moa kills) for the interim.
