Nah, my movement is to good, the human does not hit, even if I kiss his lipps (head) with my big mauth :>
2 humans with BS/Luci? No problem. But 2 humans with BS/Chain ARE a problem for a tyrant 
Oh, if it's a Tyrant in front of me, I would have already used all the tools at my disposal to get some confortable distance between he and me

Most of the times, those tools consist of :
- I'm not too far from my base and if the tyrant gets closer, I'll hide behind the turrets
- Luci jump somewhere the Tyrant can't reach
- Crouch somewhere the Tyrant can't reach
- Luci jump out of reach if a long enouth corridor ( only buys some time until I find another solution )
- lucispam while retreating to a more strategic position, often combined with the one above
The last two are when I'm really desesperate and their rate of success isn't too high
