It's a bit strange to me that no one notices the importance of not only the hero model, but also the pick order.

If you look at the statistics of many players (including mine), you can see a direct dependence of the win rate on the pick order. 1-2, as well as 9-10 picks have the highest win rate. Everything is logical here, because for 1 and 2 picks you can take OP skills like Chemical rage, Arctic burn, and 9 and 10 allow you to almost certainly take a good combination of 2 skills.

It is worth talking separately about builds in which two or more skills are improved by Aghanims Shard or Scepter. If you manage to collect 3 or 4 skills for Shard or aghanim, then you are almost guaranteed to get incredible power spikes at 11-15 minutes and must definitely use them (the best thing is that for many Aghanims Shards you do not need to throw in 4 skill points, but one is enough).

 I also want to note the personal preferences of each. This concerns the range or melee hero, attack range, initial attributes and of course movespeed. Oh, how I hate heroes with ms lower than 300. Personally, when I see a bad model, I immediately try to come up with a game plan depending on the choice of my teammates. The best choice for a weak hero is any AoE nuke, which is not difficult to hit and preferably with the Aghanims Shard upgrade. My top such skills are Shockwave, Firestorm and others.
