I was climbing with vip 0 untill level 100 playing game casualy and managing my resources very unefficiently.
Also I've left this game twice for a month each time and now I'm in top guild on my server. vip10 - so middle spender I guess.
Main thing I've learned is that the game is as hard as you make it to be by setting your ambitions too high in casual mobile app.
With all respect, if you are not super hardcore competetive type who wants be in the top, you will have no problems playing DS at your pace still.
You will get your level every week without delays as we do.
Sure you wil lhave to manage your priorities on hero promotion much more strictly.
And I can assure you once whale will got to C4 everyone others would just lose Guild Wars against them.
That will be happening untill middle guilds get their C3 at least.
If you have any douple XP runes left, I'm sure you know what to do
If you need any specific or help or advice on C4, leave me a note, I'l gladly share what I've got to this day.
