Yeah I had my first ever game with him, but as I say it was my first match. But I did play against someone who was farming his Q ability.
I tried the Faceless Void But mainly just got assists lol. Would you recommend anyone else. I want to mix things up abit
EDIT: Also that lone druid I have had 2 games with him and he was a right pain to down
When I said unlimited power I meant mana haha, very tired today. Didn't get a whole lotta sleep last night

haha.
People who use their abilities to farm don't know how to farm properly and you can wait for them to expend their mana and gank them.
First things first is to learn what items to buy at the start, don't really know how much you know about the game so I'll lay down some basic things:
1) Salve potion and a tango. With only a few exceptions you need these. As someone new to the game you will even more likely need them. Don't buy more than just one of each though, need to learn to avoid damage not cover it up.
You will almost certainly want to buy 3 iron branches. 53 gold for +1 to three attributes is the best gold to stat ratio item in the game and turns into a magic wand.
Circlets are sometimes bought too. A stout shield is great on some squishy mele heroes too, such as anti-mage. A quelling blade can be bought for mele heroes as well to help last hitting, it doesn't increase damage vs other heroes though. It's recommending on farm heavy mele heroes like bloodseeker, you might consider it on antimage as well for example. Generally though it's best to learn to last hit properly and save the money.
Clarity potions are often bought as well on a strength hero that has a low mana pool. For example, earthshaker is useless if he can't drop that stun so he needs to have that mana ready. At 50 gold there is no harm having one or two.
Always aim to buy survival stat items first. For example, you want your braced boots and you buy the boots first generally for the extra speed, then you want the strength belt regardless of if you are an intel hero because +str beats +attack speed early game when hp is low.
2) Do not buy any of the following with your starting gold:
-Boots (stats are the start of the game make last hitting easier and allow you to take that extra damage)
-Bottle (some players will do this when they take mid. It's a rookie move with a few exceptions)
- Magic wand (While a staple in many players it is useless at the start of the game because people aren't using abilities much and money is better spent elsewhere)
-Generally any big items like rings of basilis. There are exceptions to this, mainly when jungling. If you are in a lane, you need your clairty potion and tango.
3) As I'm pretty sure you already know, wards and courier win games.
