About league robots

I think you are implying you are going to spend the money. Unless you are rolling in it, I wouldn't. I mean, I could see spending the quarter of the full price of AAA console game on single virtual item... that's about 15-20 USD/EUR. But Bulgasari costs a lot lot more. Even Lancelot + Ancile (or maybe Lance+Ember but that's more expensive than Lance+Ancile together) costs more than this. Just not good value for money, if you need money for other things in life too.

The important thing to realize is: unless you are going to spend a few thousand, money will not buy you success or happiness in this game.

If you are a free player considering, which should you start saving for... After you have 5 slots, you should  get 1 Ancilot. Use components for weapons, which you need multiples of. Basically this means Scourges or Shocktrains, to put on Griffin or Rogatka or Hover, or a single one on Gareth (which is great btw, I use a Magnum-Shocktrain Gareth in FBGR Champs, and while it's not that effective, it does get some kills and some beacon and is very fun to run). Good old premium bots are Gareth (best value for 500 Au you can get) and Rogatka (superior to Galahad, for the same price), might even be worth it if you get a cheap special offer for money (if you are into spending money on bits). Bots will become obsolete much more readily than weapons (I mean, Orkans and Tarans are still superb). A component bot (except Hover, which is pretty good for the price) is going to cost so much, it's just not worth it until you have otherwise good stuff, and are ready to go to next level. You get components "for free" from chests, supply drops and battle rewards.
