Getting legendary gear can be pretty tough, especially in the beginning of the game. One of the best ways to get them is to rank high in the ticket Arena tournament and then get the bonus chest where you are guaranteed one.
Remember that you will end up replacing it after a while though it should last longer than lower quality items. You might want to save your shards if your have a hard time getting them. You can buy shard in the portal if you can get far enough for good farming rates.
The key to doing good in the Arena and Portal is to have a high squad power rating. Even if you have a high number you might not have the best set up which would get you further. The revive skill on mage weapons can go along ways.
