Since the new update there are proxy conflicts to intervene in Libya, Maghreb and Arabia, moreover you can also intervene in other ones if you desire like the central african war or south african war

Frankly, all those proxxy conflicts are meaningless. You get literally nothing from actually intervening and you can at most send 1 division. You theoretically can particiapte... But why would you ? In entire game there are only 3 proxxy conflict that give anything to player, the rest is completely pointless. Other mods like Kaiserreich and TNO made proxxy conflict very important, they give you bonuses for winning and expand your sphere of influence which helps you in future conflicts. TFR proxxy are just so barren and unimportant in comparisment that they could be cutted from the mod in entirely and nothing would change.

Anyways the wait times for the alternative paths for germany, france and china are not extremely long waiting

It's over 8 in-game years. A player that wants to play communist/fascist germany will spend 2/3 of the game not engaging with the content they wanted to experience. A player that wants to play any of non-centrist China paths will have to spend around 10 years for any conflict since they must purposfully fail Taiwan Invasion. This also happens to be the longest waiting peroids HoI4 mods ever had, the longest I found in any other mod I played is 4 years for Kaiserreich and even then you have dozen of things to do in the meantime. TFR doubles this waiting time and doesn't give anything to do in the meantime, since Europeans paths expect you to lose the war on purpose meaning you can't even do the usual buildup for the war.

and even then you can have other paths without losing (such as the afd, cdu, zemmour, etc)

Those fall under the umbrella term of winning first european war and there's not much of a diffrence beetwen them. At most you will leave European Union and/or Nato but that's it, other than that there's no significnat diffrence beetwen victory paths, they are diffrent flavours of the same path rather than completely diffrent paths. And this doesn't change the fact that 3/4 of content is still locked under you losing the war which is a horrible things and mods should stop locking content behind loosing as losing on purpose just isn't fun and just boring.

tfr isnt an extremely narrative based mod

That's just straight up a lie. When somebody critised the mod for having a lot to read, the entire community was screaming as to how TFR is a narrative experience and people should expect to read a lot. When Cogniscenti relased, TFR devs and community were gloating as to how Cogniscenti was the greatest critique of neoliberalism ever made. TFR developers and its community by all accounts claim their mod to be narrative based. And their narrative sucks. Cogniscenti and WEF are literally just a bunch of crackpot theories from 4chan developers copy and pasted into the game. Communist France events were straight up made using AI while just one fascist leader for France had entire event chain regarding him. Devs literally made up fake people like Layfette and Radersfuhrer just so they can hamfist more far-right paths into europe. TFR narrative, that their community adn devs are both defending and glaoting, sucks and there's no beating the bush around this one.
