On the topic of "MOBA" and DotA: Well, DotA is a MOBA if we search for the word - I also dislike it as a therm, because it could include hundreds of games which have no actual connection to each other, but it's already used to describe games in the same genre as DotA, LoL and Smite so I don't see the problem of being used as such. In therms of balance: I think that quite a lot of the changes are there just to remind some players about certain heroes, to seen as 'we are doing work' and to push some heroes in said direction. Most trivial changes (like +/- movement speed or armor) won't influence the game that much, but some changes which usually people pass easily can drastically change the flow of the game. For example - the Bounty rune introduction - their first iteration at the river rune just so that both heroes would have access to refill their bottle instead of being luck-based until the most recent changes - four of them being spawned every 5 minute completely change the strategy, pre-horn movements and support move patterns over the map, the importance of map control and similar things while quite a lot of players still don't get it or just adapt to it without put it into consideration as something of importance. This big changes have their good and bad points but it's still a progress, because after something is implemented it's putted in their right place over time and the game feel completely different and 'fresh'.
