How about every other tooltip in the entire game?

"Increases the damage you deal to target by 5%." would be correct, as you need to have a preposition in there. You do not "Drive 5 miles closest city." ... you "Drive road 5 miles to the closest city." (missing 'to' and ' the' in there.)
I do not believe you know what you're talking about. While the word 'target' doesn't necessarily need a 'to' in front of it, that's only in cases when it's used in something like "Let's target a 5% increase in sales."... That is clearly not what is being used in this instance.
"Increases damage you deal (to) target by 20%" makes absolutely 0 grammatical sense without the 'to' in there. Especially when you consider that pretty much every other tooltip in the game that references something done "to a target" has the word "to" in it.
If you truly wanted to be anal about having it grammatically correct, there should be a 'your' in there. "Increases damage you deal to your target by 20%" would be perfect. But there's not always space in the tooltips to have that, so sometimes "your target" gets truncated down to just "target", since its heavily implied. In cases where something is done to someone else's target, it specifies that.
I cannot believe that I'm arguing about this... This is just like the time I reported an Alchemist leve back in 2.0 having the wrong level, because it used a level 25 item but could be taken when you were level 15 and had 0 chance of creating the item, and people on this forum tried to argue that it was meant to be that way as it was a design choice, and a moderator stepped in and moved my post to 'not a bug' because 'this sounds like a discussion on gameplay'... but the very next tuesday after I reported it, the level was fixed.
I'm just not going to bother reporting anything in the future, including the 30-some odd items that have spaces at the end of their name when there shouldn't be one (causing a double __ space when you link it in-game and have a space after <link>_) because I shouldn't have to defend my the obvious reason for why it needs fixing to someone else who thinks they know better, or tries to argue that its meant to be that way.
Good day!
