To be honest, that's way too high at a point where CEXs are offering no-fee fiat deposits. If we want DEXs to take off, it must do so on a base of more than just screaming 'DECENTRALISE!!!" Consumers need to have a real incentive to start using them. On that, the fee should be 0.2%, max.
Wyre is only for the FIAT gateway and needs to make money. Centralized exchanges with FIAT gateways subsidize deposits to be "free" because they know they'll make their money back on the trading fees. Wyre doesn't have that ability.
