What you did wrong:
1: You're in a clan which you seem to have given up on, and you want to join another clan since the activity seems to be at a low-point.
Looks good so far
2: You send very obvious signals that you want to join another clan. This clan happends to be one that appreciates loyal clanmembers.
Yes yes, 1 and 2 seems to be very nicely linked, all good.
3: A guy who's in the clan, a guy you haven't seen for months apparantly, appears out of the blue and tells you the clan is coming back together after you made a public thread about wanting to join another clan.
It's getting a little shady, and you got a dillemma on your hands, we can understand. Nothing really wrong from you yet.
4: You tell the people in the clan you expressed a want to join that you wont join them yet, you will stay in your current clan, even though you don't believe it will survive that long, and it wont be any big either. You also say that you should be considered to be "on hold".
This is where things turn ugly. You come across as arrogant when you make that statement, also (V) from the looks of it, seems to be your back-up clan after 1st. And even though you seem to not have much faith in 1st, you still choose them over (V). Now, I am a little confused, but how on earth do you expect (V) to want you to join them now? First you start a humorous thread about joining, and they seem interested in it, and then you hit them in a face with the fact that your old clan may get ressurected by someone else, so (V) will have to wait a while for your services.
That of course may not be the truth you want to hear, so if you want, here's an alternative truth: You didn't do anything wrong, and the world is out to get you.
