Garen needs some buffs on Q and R (my opinion)

Let's go straight to the point ... At this moment Garen not if he is doing really good, he has always had difficulty reaching the enemies, especially if equipped with slows ... Garen becomes completely still and you can not move ... I'm talking about champions like Ashe, Ziliean and the like. So I was thinking in increasing the speed of the Q and giving immunity from the slows for 1s and moreover, during this immunity, if a slowing effect is applied within that second, EVERY slow is completely canceled. In this way, this hypothetical buff, should give Garen more finials to chase the enemies or simply to get .. On the enemy ... And I refer to you Ashe. So I'm here, to offer you what I have in mind about Garen. The buffs that would be ideal (always according to me) is the Q-buff for speed, at least a 45% speed increase would not be bad, and then put a new effect, which is to give immunity to Garen from all kinds of slowdown for 1s, during this phase of immunity, any slowdown applied will be immediately canceled. In this way Garen will have more chances to chase enemies in the event of a slowdown (it might seem repetitive, but I want to be sure that the concept I have in mind is clear). The other buff is more ... Subjective ... In the sense that it concerns the damage of the supreme, which should increase both the basic damage, the percentage and also the passive of true damage. Here are the numbers: Base dmg level 1 = 175 to 250 level 2 = 350 to 450 level 3 = 525 to 675 The percentage level 1 = 28% to 32% level 2 = 33% to 36% level 3 = 40% to 45% True damage = 1% to 1.5% (I had also thought of putting a 2%, but then, observing the buffs, it would have been a bit 'too much.)

And here it is, this is what I had thought, so what do you think? Do you like or Do not like it?
