Then there would be trackers/parsers that use streams/videos, and can't be stopped. It's just "What if they ban trackers?", but applied to servers instead of universally. External trackers will be written and used, instead of the game's provided tracker. You don't get the benefit of "tracker players will move to a different server" because no-one is going to start over from level 1 just because their server changed it's mind eventually. They'll just write the ACT (not Ashes Client) plugin, and start parsing their combat video (on their other PC, if need be).
Remember that the goal of the "Pro Tracker" group here is not to have trackers for themselves. It is to remove their own competitive advantage by letting everyone have them, so the game is more fair. The ones that just want their own don't bother to post here, because you can't stop them.
The other idea proposed by the "Pro Tracker" group here, as you know, is to have trackers be guild-based. This lets people who want to "not be tracked" easily group with like-minded individuals who are encouraged by the system to respect their preferences.
This only works if there is an in-game tracker provided (which doesn't happen if a server, or even node, eventually votes to turn it off).
This provides a protection against more powerful external trackers by making it not worth the effort to write one. As a result, the "I will join a guild without the tracker perk" means the tracker will respect your limitation.
This is possible only because of the convenience of having a tracker provided. If it is more convenient to join a guild with trackers enabled, than for one player in the world to write a tracker for Ashes, then that is what will happen.
If an in-game tracker is
not
provided, is later voted away by the node or server, or is made too difficult to access by players who are interested, then an external tracker will be created because it is no longer pointless to do so. This works for tracker players, but removes ability for others to avoid trackers by choosing to play in a guild without the tracker perk, because there is now an external tracker available will not respect that limitation.
It's work to write an external tracker, but it's not
that
much work, and once one exists it will be shared. If you make it more convenient to not bother, you can do thing like have tracker-free guilds. If you don't, you lose even that option.
And so to finally address your question directly:
If a guild has a choice between "leave a node we have each invested hundreds of hours in, because they now voted to ban trackers" and "our programmer spends 30 hours writing a tracker as this week's hobby project", they're not gonna choose "abandon our node".
If a guild has a choice between "leave a server we have each invested thousands of hours in, and maybe have world firsts on, because they now voted to ban trackers" and "our programmer spends 30 hours writing a tracker as this week's hobby project", they're not gonna choose "abandon our server".
In any case where you say "no trackers allowed", or even "we'll only give you one if you give up your home" (node/server/etc), you're going to have external trackers that you don't control. The only "lever" you get is the temptation of convenience. It's not
that
hard to write an external tracker.
