In terms of content there is no difference. Legendary edition is just a bundle of the base game with the DLC, which or may not be a different price.
Yes, on mobile I find certain text to be too small. The game has a pinch to zoom feature, but new window boxes (like equipment stats) will always rescale to be constant size regardless of zoom level so the text is always small.
As a workaround I found the native Android feature called "Touch zoom" works well. With Touch zoom turned on you can triple tap then pinch zoom to enlarge the text size for things like equipment items. The only downside is that there is extra input delay because the device is waiting to see if you're going to triple tap. This makes moving and fighting monsters more tedious. To fix that I downloaded the Automate app to add a button to an assist button that turns on Touch zoom when Titan Quest is open so I can use it when reading stats and turn it off when fighting.
It's also on the Google Play Store for $7. https://play.google.com/store/apps/details?id=com.dotemu.titanquest&hl=en_US&gl=US

Hey Rhokk222
yes the patch is released on Wednesday the 27th, not sure why the patch release is pushed that far. Switch release isn´t happening before July tho as far as I´m aware if no delays happens to the release.
So not quite sure how you see those two things mix ?
