Mbox wiping the whole team right at the start of WG

So i know that mboxing is not bannable etc, but one player ruining a bg by effectively wiping the whole team at the start as you get ported to the WG fortress is disgusting. I dont mind mboxers, but this is bit too much. It gives the other team very unfair advance and its basically 1 person having the result in their hands. It says that that Frostmourn holds the brand of warmanes quality but i think this is a big ducking stain on it.

It's a design flaw.

You can be smart and wait 19s before accepting the que to completely avoid it.

Every class can do something with similar effect that freezes, damages or keeps people in combat at the start of wg.

As mentioned above, this is a non issue as you can easily avoid it by waiting 10-15 seconds to join WG.
