I made this little simple script a long time ago. It helped me clear raids SIGNIFICANTLY faster. Spam clicking + speedhacking allows you hit a gate up to 4 times in a turn thus killing gates really fast even a weaker weapon. You can just go afk and the gates will be dead when you get back, no tiring mass clicking.
Alternatively, you can use netlimiter to create lag and do 200-500k+ in one turn, as mentioned by someone below. Netlimiter is very easy to use, do a google search. I'm still experimenting with numbers but I limited dl to 20 and upload to 20, I just spam lots of clicks and then disable the limits, I can do 200+k in one turn.
How to use:
1. Stand next to gate
2. Set speedhack to 18 in cheatengine
3. Run script
4. Put your mouse cursor on the gate
5. Press F6
6. Kill gate very fast
7. Press End to exit
8. Click thanks if it helped you
