Bro, Eclipse will have increased speed while its ability is active

Something is off :-)

With Sprint ist speeds up but not with the ability

I've noticed even with the epic Cloak Speed boost implant lvl 5 and it still only feels like the regular fully charged basic sprint boost every mech gets. It's been like this for awhile now for me. I'll even use a Neymar pilot and see no difference from the regular basic sprint boost. The problem might be that I'm playing a mobile game on a mobile device but the game is tuned for pc players only. Just my observations over the years. 

I have a maxed golden implant for Phase walk speed, and I can barely feel any speed bump. It walks faster with sprint than with the ability

I think the devs had revoked the extra speed boost ability for Eclipse (probably to nerf it). I don't have one, so I am not sure what causes the problem. I'm sorry if I have provided any wrong information
