They've already added a metric ton of new weapons. Bayld weapons, Wildskeeper rieves, Skirmish, Delve, etc. There is a decently large selection and each of them will get an associated skill+. You don't need two weapons for each level. Use a Skirmish and a Bayld. Skirmish and WK. Delve and WK. Eventually it'll be RME and Delve as the highest tier.

Edit: Even more weapons to come in the next update.
