Hm...let's see...
1. Laning is much more difficult in DotA than LoL overall. Squishy late game melee carries (like spectre, pa, etc.) need babysitting to gain the experience, last hits, and levels to transition well into late game. Common melee solo laners are doom, clockwerk, dragon knight, kunkka. These heroes often have high hp/armor (doom, dk) or good harassment/farming skills (clock, kunkka). It is definitely harder overall for melee heroes, but it isn't impossible to win your lane with a couple of good ganks or an early tower push from your team.
2. This is a very generalized explanation, but agility + strength heroes have very low mana regeneration and only 1-2 skills that use mana. Agility heroes will typically invest in attack speed items and damage. Strength heroes will invest in armor/tanking/regeneration/spell reduction items. Intelligence heroes will invest in mana capacity and regeneration. Again this is a veryyyyy broad explanation.
Almost all skills require mana with the exception of things like huskar's burning spears and his ultimate...stuff like that. But even in the beginning phases of laning, I feel that you can spam your skills indefinitely to harass the enemy heroes without having to worry about not having enough mana a minute later when youre getting ganked or something...whereas if you're spamming your lvl. 2 stun against someone in your lane constantly to "harass" youre just going to get dominated when a gank comes...even if you're an int hero and have a large mana pool. Often times the mana costs on the spells of int heroes are higher...so I guess that's where the mana balance comes in early game.
Cooldowns cannot be reduced unless you have the item "refresher orb" which completely refreshes all your skills ONCE every 210 (I think) seconds. But in general cooldown reduction isn't a game mechanic that's highly implemented in the game. Oh yeah and death prophet's witchcraft reduces all the CD's on her skills...but that's about it.
3. DotA has some flexibility in the builds as well...but investing in a wasteful item in early/mid game can push back your farming for the really crucial items by 5-10 minutes depending on how the game is progressing...In a 50 minute game..this can be huge. On a side note, the item builds can be tailored to your team's strategy as well...If you have a weak late game line up you can go for a game winning 30 minute push and end the game there with the right items.
4. No comment.
5 & 6. Map awareness is the same in both games I would say. Warding is very important in both games as ganks can come from the forest at any point in the game. When heroes are missing from the map it's pretty obvious what they could be doing (healing, buying, jungling, ganking) and wards help with this.
Map CONTROL comes with the mobility of the team and your towers/where your defenses lie. This aspect is clearly lacking in LoL. If I die and buy-back in LoL...wth am I going to do? TP into the fight immediately? I can't do that......In DotA a buyback would be HUGE and potentially game changing because there's always that factor of that really buff medusa that you just took out with all your ults? Guess what? Her farm was so good she's just going to buy back, TP in, and own your faces.
7. Tree eating, fog of war, skills that go through trees, skills that raze trees, the 3 seconds it takes to tp somewhere...So many factors go into juking and I feel like it was all lost in LoL.
That is all. hahahaha
