I know there still is a big crowd of angry people who wants Techies completely out of the game. I'm neither a Techies enjoyer too.
But Valve did a pretty great job to find a good solution while reworking Techies. Without sacrificing his identity, playing Techies still feel like Techies yet his extremely annoying game ruining play style has been removed. Instead he has now become a real team player most of the time. He's become a true support too compared to him playing his own games alone somewhere else on the map previously while ignoring what's happening in the lanes or to his team, ultimately became an asshole to both teams as the games progressed, and then hated by both teams. Now he's not that asshole anymore. He is now just another disabler + nuker who joins team fights; which is normal nowadays and seems pretty acceptable to me.
Some of you might still disagree with me. But I'd like to appreciate Valve for this change. Feel free to share your thoughts.
