Wow, this was beginning to look like one of those stories that begin with, I have a load of cash (or gems) burning a hole in my pocket (or overflowing my coffers), but I need some spending advice, and all the investors and their cousins come knocking on your door, pretending to be the best man at your wedding, and tell you how to spend that fortune by investing in their ventures and hedge funds.
Fortunately, this isn’t one of those stories, because the friendly players in the S&G group do not gain anything by giving you advice on how to spend your gems aside from the feel good feeling that they helped out a fellow E&P player. I suppose if any one would like to make a bad suggestion for you, is that they are afraid that by giving you good advice, and you gained from it (e.g. better heroes), they will one day get raided by you, the new and improved you, and you walk away with their cups. But I have a feeling most of the players don’t really think this way.
Any way, I’ve played for a year now (in fact, I think today is actually my one year anniversary), F2P + $3. I’ve accumulated enough gems through daily grinding and mission fulfilling to get enough gems to do a 10x pull a few months ago, in fact, I think during the first month Atlantis was available (either Aug. or Sept. of 18). Now, I was faced with the same decision as you are now, spend a little less Gem and do a 10x event/elemental/seasonal pull or the full 3k for the Atlantis 10x pull). I eventually did the Atlantis single 10x pull because I figured the pool is a bit wider and can get chances at past HoTM and current HoTM.
Lo and (Cyclops: Behold! Optic Blast!) - Out came Boldtusk (dupe), Rigard (not dupe), Chochin x 3, Namahage x 1, Ameonna x 1, and the rest were duplicate S1 3s. No 5, past HoTM and no bonus HoTM.
The next time I had saved up another chunk of gems (last month), I decided to do a 10x Troop pull hoping for some 4* red/purple, all 10 were 3* and some were duplicates.
So aside from the fact that RNG Gawds still hates me. Looking back, that Atlantis was actually my first 10x pull of the game, I’d probably still have done it for the novelty factor and the fact that I would at least get a Mat out of it (it wasn’t gloves). But perhaps the next time I get close to gem counts again, I might choose a challenge event to see if I can get a Guardian, a Knight, or Fable character, simply because I have no heroes that I couldn’t get from TC20 (aside from Atlantis ones) on my roster, and I am looking for some flavor to it.
Good luck in whichever you choose.
