No it's not a good idea at all, I explain....
When you transfer a an item from Class 2 in Tier 2 you would lose 1 Tier in the process,
That means is that you would upgrade an item to Tier 2 costing you min. 5,75kk plus the cost of transfering 5kk
Also you will have to spend another min. 5kk to upgrade it again to Tier 2
Any item Class 2 is worth much less than all the money that is going to cost you doing that.
Also if you want upgrade a item Class 2 to Tier 2 the only way is Fusion, Transferring is not possible.
Also
You can't transfer Tier 1 it's only from Tier 2 that you can transfer to another item. (So you can't transfer Class 1 items)
