Havent played dota 2 yet, but if may i ask, the buying items there? is like dota 1? (different shop for each type of items) or like in HoN (a drag down something)
dont know about LoL havent played it yet...
It's nothing like Dota 1. Surely you've seen some screenshots from the shop on the net? It's basically one single shop where you buy your items. And you have different tabs to choose from, like "Upgrades", "Weapons", "Support", etc.
Dota 2's shop is just like the normal Dota's, the only difference is that it's improved and easier to use. Each shop in Dota 1 is represented by a category in the menus in Dota 2.
You will get used to it pretty fast, and you can build your own recommended items, which is amazing. Don't want to finish building an item through browsing the shop menus or usinga large amount of hotkeys? No problems, you can stick all the items you will need on the UI for easier purchasing.
In my opinion, Dota 2's shop is great. There's many things to improve about it yet, but with enough feedback those things will be addressed.
