Yes, this tournament format will make it shorter.
In my opinion there is no need to delay it.
On September another tournament, or a different event, could be organized.
This is the “summer” tournament.
In any case, if it will be succesfull or not, mostly depends on how many teams will be signed.
If something could hurt the tournament, more than summer sun, sea and holidays, it is game population imo.
What I can suggest is just this: do not be scared, do not sign as Free Agents, but try to make groups with friends
(or try to make friends by making groups
).
There are 2 brackets, for veterans and less experienced players, so risk you get stomped (which, must be honest, totally breaks the fun) is a lot lower.
Also this is for fun.
Fury tournament, apart few exceptions, was pretty friendly, so just join for the fun and nothing else.
It is a game. And you can for sure gain something - whatever is some funny moment playing with friends, shards or some PvP experience and skills - while having fun.
Also if game totally gets one sided, most probably the other group will accept to end it fast by delivering flags, so don’t be scared of results.
Some of the games on Fury that ended with stomps in many cases ended like that because the loosing team explicetely asked to keep playing (we did so for example vs IT, because we wanted to practice).
@MyStygga: I’m curious of how many teams signed or contacted you already.
We are ready to sign, just slacking a bit… because of sea, sun, holidays… 
super even?
