Sadly, its not 40ias, but has 2 useful skills and 4+max damage, which in my opinion is better than the one that is 40ias and 3+ mindblast. Light sentry allows for longer range stun locking and fhr animation activation, which lets you catch people easier. 3+ Mindblast, is ~30 damage more per spam (5 damage per after pvp penalty; and 2.5 after 50% DR is applied).
PS. Light sentry has longer range than death sentry. Death sentry is glitched and has a shorter range. I've tried it, but if anyone cares enough, they can test it themselves to see what I mean:
1) Lay a light sentry, find its maximum hit range.
2) Lay a death sentry in the same spot, you will find that it will not hit at the same range, but requires the opponent to be closer to you.
