Which is a legacy from subsidies to kick start a new technology and it has worked . Wind is now far cheaper and stands up on its own without subsidy . <| sep |> Any learning drivers here , please take notes . lol . <| sep |> Yes it is . Order went through . <| sep |> Do you think the 1070 would fit in this case ? <| sep |> When talking about best heroes let ' s focus on the ones you can get by promotion , which are Mamba dps , archer , Benjamin dps , wizard , Joan tank , warrior , Alexander tank , paladin , Mew 1 block healer , priest and Yeo 3 chain healer , useful for block generation . Obviously there are also a lot of Premium Heroes really good but there you can ' t really aim , but spending 50 gems whenever you get them on 10 contracts bundles is your best investment and will be for quite long . Also you may always wait for some rate up that can give a bit more chance to get certain heroes . Other good ways to invest gems are the extra slots for Heroes , Bread , Weapons , etc . as soon as you start to need more and you don ' t want to give up on anything you may need like heroes yet to be max leveled for the first time , high level bread , etc . . Don ' t spend gems on retrying stages , rerolling stuff like hero promotion , is just a lost bet against a trolling RNG , buying gold and so on . Just go for the heroes until you have a good heroes pool .
