I don't mind a token system, but at the same time I'm not particularly fond of the fact it will be for lesser gear. SE did a similar system in ffxi, but put in high requirements and left the gear at 100% strength. In Voidwatch you would need 5 of the same token to get 1 drop and this was done due to the individual treasure chest system where people would end up getting multiples of the same item but could not give it to others. These items had very low drop rates (some could literally go 200 fights and never see the drop while others might see it every 5~10 fights).

Then SE introduced a new type of Nyzul isle that is very highly garnered to speed run and extreme amounts of luck. A patch introduced a token system so that after reaching a boss floor 25 times for floors 20/40/60/80 they could get 1 piece of gear that dropped off those boss. On Floor 100, due to difficulty to reach this consistantly, you were given 1 full token per win on top of what ever dropped. The gear was 100% stats and this still worked fine (so long as players did the content legitimately the projected distribution of the gear was still within acceptable means given the quality of the gear).

I honestly don't see a problem with creating a system where the gear is still 100% but you need a certain number of tokens to acquire it. This still makes it worth while for players to complete the content over the course of time and rewards them properly for doing so. However, this is also highly dependent on how hard the content is also. Even with it limited to 3 times per week, the promise of at least 2-3 rare drops puts distribution up fairly high if the content is consistently completable. This would be about the only reason I could see that upholds that the token system is for lesser gear versions of the rare drops.

I know currently many of the rare gear is set in a fashion that Speed runs are the way to get the items, which would support this type of system to an extent, but at the same time if the new content on a 2 day timer cool down is still catering to this fashion of play wouldn't it be better to keep the token gear still at 100% since the difficulty is still relatively high in meeting the requirements even to get the rare gear to drop in the first place?
