You can finally jump now, what a concept. The concept of swap force chars was such an interesting twist and also led to some interesting gameplay options. The balancing is such a joke, with some Swap Force chars being so OP that it does kinda make the game feel pay to beat it more easily. The 100% completion aspect is kinda reliant on Swap Force chars, but you also need Giants as well. At least for the dual gates, you can just bypass them with a 2nd controller and 2 skylanders of the elements rather than relying on a Swap Force char.
